If Big Brother's Mark Byron looks at all familiar to you, then there's probably a good reason for it - as he's certainly no stranger to reality TV.
The fame-hungry 24-year-old has built up a strong background on the small screen, and his last high-profile appearance in front of the camera was on The X Factor back in 2011.
Auditioning in front of a panel that included Kelly Rowland and Gary Barlow, he sang Rihanna's 'Only Girl In The World' and threatened to leave the country if he got four 'no' votes. Sadly that fear became a reality when the judges unanimously rejected him.

"You didn't sing in tune once today," the Take That frontman told him.
Two years before that, at the age of 19, Mark was on the Sunday morning fave Shipwrecked over on Channel 4.
He wasn't on the winning island so didn't get a stake of the big-money prize - but perhaps Pauline gifting him with £5k tonight has gone some way towards making up for it!
