Westlife fans have been whipped into a frenzy by a report claiming a reunion is "definitely happening".

The Irish Sun has quoted a source as saying the band will be getting back together, but without original member Brian McFadden.

The source told the newspaper: "It’s signed, sealed and delivered and it’s definitely happening - and it absolutely does not include Brian McFadden.

"The other guys have been lined up to return to the studio and record some new songs and tour dates have even been organised, so it’s definitely going ahead this time. There’s been a lot of speculation, but this time it’s a done deal and contracts have been signed."

The reunion would mean the four-piece playing their first dates since their farewell shows in Croke Park in 2012 and their first new album since 2010's Gravity.

The newspaper also reports that the group have snubbed former mentor Simon Cowell by signing with Universal for the reunion.

A source said of that decision: "Simon wanted a Westlife reunion but only with something extra to bring fans back.

"That meant Brian and his unpredictability. It would give the Westlife reunion the tension it needs."

However, the band allegedly decided to reactive the group without McFadden.

Westlife reunion reportedly happening - without original member Brian McFadden

Although confirmation of the news has not yet been forthcoming and the four lads have been keeping schtum, the report has fired up their fanbase.

Westlife announced they were splitting "amicably" in 2011 after 14 years and 26 top ten hits.

Since they parted ways, Shane Filan has released three solo albums, Nicky Byrne has presented a show on 2fm and co-hosted Dancing With the Stars, Kian Egan has appeared as a judge on The Voice of Ireland and Mark Feehily has released two solo albums.
