Sam has gone on to appear in every series since, however she obviously feels as though it is time for a change so has signed up to Celebrity Big Brother!
Last year, Sam's romance with TOWIE co-star Joey Essex was a central storyline and the cameras were even there when they got engaged.
Sam and Joey split up just weeks later, however she recently admitted that she "still loves him".
As a sideline to the show, Sam and her sister Billie - who is pregnant with her first child - run a clothing shop called Minnie's in Brentwood, Essex.
Sam had attempted to keep her CBB stint a secret, but former TOWIE star Amy Childs let the cat out of the bag earlier today when she confirmed her appearance on Twitter. Oops!
