Caroline's night on the Styles

The 17-year-old One Direction heart-throb had arrived at 32-year-old Caroline's house at 10pm on Monday carrying his overnight bag.

The Xtra Factor presenter had been out earlier buying food and wine for what appeared to be a romantic evening in with her toyboy love.

And when Harry emerged at 9.30am yesterday he looked tired and dishevelled ? with his hair even more ruffled than usual.

Caroline came out of her home in Muswell Hill, North London, two hours later in dark sunglasses, tight plum trousers, high heels, carrying a big brimmed hat and wearing a broad smile.

She and Harry ? whose group came third on X Factor last year and are in the album charts with debut Up All Night ? have been on a string of dates in the past month. Caroline insists she has no worries despite the 15-year age gap.

She said recently: "I keep thinking, 'What have I done wrong?' But I haven't done anything wrong. What's hard for me to get my head around is people saying it's disgusting. I don't think it is."

Caroline added: "If two people like each other and get on, why does anyone else find a negative in it?

"I know it's human nature to gossip. But why say it's bad? No one's being hurt."

Caroline has also received hate mail from One Direction fans. But she says it does not worry her.

Prince Harry and Chelsy Davy party the night away at The Brompton Club in Chelsea

Most people avoid their exes like the plague.

But Prince Harry and Chelsy Davy attended the same venue last night, both soldiering on until 2.30am.

Club-goers said the couple greeted each other warmly inside The Brompton Club, situated in the exclusive area of Chelsea, London.

Sources said the prince and his ex, 26, chatted without any obvious awkwardness, although it is unlikely that his recent liaison with a tattooed cocktail waitress would have been a topic of conversation.

Socialites: Prince Harry and ex-girlfriend Chelsy Davy attended the same venue last night, partying until 2.30am at The Brompton Club

The pair were joined by an odd mish-mash of guests, including Dizzee Rascal, David Haye and Louis Walsh - hardly known for his wild ways.

Harry, 27, opted for a smart-casual look, choosing to wear a suit and black shoes, but ditching the tie and leaving his top button undone.

Former flame Chelsy, 26, wore a a festive red berry mini dress, teaming the frock with black heels and a winter coat jazzed up with a purple lining.

No bad blood: Chelsy looked happy to see Harry and shot him a beaming smile, before he chatted to his sister-in-law's mother Carole Middleton

Eyes meeting across the room: Harry seems to find his ex-girlfriends' gaze despite several people sandwiched between them

Earlier in the afternoon, they came into contact at The Henry Van Straubenzee Memorial carol concert at St Luke's Church, also in Chelsea.

The pair were seen greeting each other with a friendly hug as they attended the event of which Harry is a patron for the charity.

They were also joined by Kate and Pippa's mother Carole Middleton.

The couple appear to have had a complex history, with their turbulent relationship causing them to split four times between 2004 and 2009.

Earlier this year, there was speculation they would rekindle their romance once more, however Harry publicly stated he was '100 per cent single'.

Then at his brother's wedding to Kate Middleton in April, rumours circulated that Harry was more interested in flirting with maid of honour Pippa than watching Prince William take his vows.

Strange guestlist: Louis Walsh attended, alongside David Haye and Dizzee Rascal

Harry has just returned from the US, where he underwent two months of intense military training in California and Arizona.

A rep for Naval Air Facility El Centro in El Centro, said: 'Captain Wales has completed his training in the United States and has returned to the UK.'

Going home alone: Chelsy didn't seem to be in the mood to continue the party and caught a taxi solo

Time for bed: Chelsy avoided posing for photographs as she headed home

Frankie Cocozza reveals the extent of his drug use 'My six night cocaine bender':

Admits he was wasted on the drug for almost a week straight

Reveals he has slept with seven girls since being on the reality show

Former X Factor contestant Frankie Cocozza has revealed he's not a drug addict but an 'idiot' instead.

The 18-year-old hopeful has opened up about his bad behaviour that led to him being booted off the ITV reality show.

Cocozza revealed that he has taken cocaine six times and said he will regret his action for the 'rest of his life.'

But despite being asked to leave the singing competition, Cocozza was already spotted back in London yesterday heading to Holborn Studios in North London.

He emerged from the building tonight to have a cigarette and seemed particularly pleased with whatever had been going on inside as he flashed the camera a huge smile and gave a thumbs up

Speaking ton today's Sun newspaper, the big-haired wannabe explained that he felt guilty about what he'd done.

I feel bad about letting the fans down and I'd like to apologise to the people who voted for me,' he said. 'I'm really, really sorry.'

However despite ruining his chances on the X Factor, Cocozza admitted that he couldn't guarantee that he will stay away from drugs in the future.

The hopeful - who has admitted to trying the illegal high mephedrone in the past - said: 'I can't see into the future so I can't say that I'll never do coke again.'

Cocozza, who lives with his mother in Brighton, East Sussex, also revealed that he has slept with seven females since starring on the X Factor and admitted that it was easy.

Going out just got mental as women would just come up to me,' he admitted.

'I didn't really need to dig out the chat-up lines which I used. It was so easy.'

However the youngster's downfall was last Saturday night which he spent with blonde Becca Hills.

She was at his side during the hedonistic night of passion and partying that led to his axe from the X Factor.

The 19-year-old has spoken out on the scandal.

Hills is cagey about the details of what went on inside the West London flat she was seen entering with Cocozza on Saturday night, but admits: 'Some stuff happened between us, it's a bit embarrassing to talk about.'

Cocozza was pictured topless and sitting with a female companion in the window of the flat where an after-party took place over the weekend after a night of clubbing.

But despite their liaison, Hills insists: 'I don't plan to keep in contact with him. There's no future between us.'

Speaking again to The Sun, Hills, insists: 'I never wanted him to get in trouble. He seemed a lovely guy who likes a drink.'

The teen and her friend Katherine Holland, who was also pictured at the party, say they did not witness the singer taking drugs.

Holland, 19, told the Sun: 'We didn't see him do cocaine, but it's not that we followed his every move. Drugs are for losers, we never touch them.'

Cocozza and his entourage were pictured carrying crates of beer into the flat after a night of partying at Funky Buddha nightclub.

On the X Factor results show on Sunday night, he admitted he'd only had 30 minutes sleep while some claimed he was still 'off his face' during the programme.

It later emerged that production staff overheard him boasting about his 'cocaine-fuelled sex session' on the Saturday night, and reported him to the show producers.

Less than 24 hours later, it was announced that he was leaving the show.

In a separate report, it has been alleged that Cocozza funded his wild partying with money paid into his account by FremantleMedia, who produce the X Factor.

The company is said to have paid each other contestants a 'discretionary payment' of £3,000 following their work on the M&S Christmas advertisement, the Mirror reports.

Marks & Spencer, which has a sponsorship deal with the series, did not pay the contestants for the 'When You Wish Upon a Star' ad campaign.

'Frankie is a normal 18-year-old,' a source told the paper. 'He got the money and it was burning a hole in his pocket. He couldn’t wait to blow it on partying.'

Cocozza was still spending up a storm on Wednesday after returning to his home in Brighton.

The wild child went shopping at shoe store Vans, where he was spotted handing over a wad of cash for a pair of trainers, and also stocked up at All Saints.

A spokesperson for FremantleMedia was unavailable for comment.
