But it all fizzled out before he went on tour to America.
So exactly who is Emily Atack?
Emily, 22, was voted FHM's 10th Sexiest Woman In The World recently - one place higher than Her Royal Hotness Pippa Middleton.
Take that, P-Middy!
She had a brief fling with comedian Russell Kane, 31.
They were caught kissing in the back of a cab in April after the premiere of her film Outside Bet.
She hit the mainstream with Dancing On Ice in 2010.
However, after being eliminated from the show, she threw a temper tantrum and was pictured hitting a taxi and sobbing uncontrollably outside the studio.
There's no shortage of entertainment at her family reunions - her second cousin is only Beatles legend Paul McCartney, 69.
