X Factor’s Sam Callahan whips off his top in front of a star-studded crowd as he prepares to enter Celebrity Big Brother and face ex Jane Park
X FACTOR star Sam Callagan has got pulses racing after whipping off his top at a charity fundraising event.
Sam was performing at this year's R U Coming Out bash when he decided to strip off and give revellers a look at his buff body.
The singer, 22, is a regular gym bod and has beefed up considerably since appearing on the 2013 series of The X Factor.
Before attending the event, which was held at London's Vauxhall Tavern, Sam shared a naked torso shot on Instagram.
Alongside it, he commented: "Performing at the @rucomingout party at @thervt today! Should be a giggle."
Former barman Sam, from Essex, recently hit the headlines after a whirlwind romance with Lotto winner Jane Park.
The pair are now set to star in this year's Celebrity Big Brother, where they could confront each other following their bitter break-up.
A source told The Sun Online: "There’s been talks about Jane going into Big Brother, originally she wasn’t interested but then she heard that Sam was going in and everything changed.
"Jane’s a feisty girl. If they both went into the house he wouldn’t be able to get away from her."
Meanwhile, Sam's performance at the R U Coming Out bash, held by the LGBT coming out support charity, went down a storm with guests on Thursday night.
Holby City actress Gemma Oaten offered herself up as a co-host for the night and was snapped looking lovely in a floral jumpsuit.
EastEnders' Danny-Boy Hatchard also showed his support to the charity along with TayTay Starhz, who is famed for snogging Zoe Ball.
