Simon Cowell has reportedly blanked Westlife since the announcement that they are to split.
The band haven't heard from their former boss, who they were signed to until 2011, but have spoken to Louis Walsh after confirming plans to bow out with a farewell tour in May 2012.
Kian Egan told the Daily Star Sunday: "No, we've not heard anything from Simon at all. We aren't on his label anymore and I'm sure he's really busy in America, so I'm just guessing he hasn't had a chance.
"Louis [Walsh] kept trying to change our minds, saying we were mad to be calling it a day and we were throwing something amazing away. He's probably right to be honest but we all want to try something new."
Speaking of former member Brian McFadden, he added that the band debated whether to leave his vocals on their upcoming Greatest Hits collection.
"We were asked if we wanted to re-record his vocals for the Greatest Hits album by the record label," he explained. "We discussed it and we were like, 'No, we don't want to take him off'. But even though we want Brian's vocal on the record, bringing him back would overshadow what we have done as a four-piece."
Egan added that they had been offered "big bucks" to reunite with McFadden. Nicky Byrne has also stated that their record label had offered them more money to stay together.
