Lauren was one of the original TOWIE stars, appearing on our screens for six series until deciding to leave and focus on other projects.
As well as watching her glamorous life unfold on TV, we were all mesmerized by her rollercoaster relationship with then boyfriend and former fiancé, Mark Wright, who is now engaged to Michelle Keegan. Mark and Michelle were together for a whopping ten years before calling it quits.
Since leaving TOWIE, the star's barely been out of the headlines. She's got her own beauty brand, Lauren's Way, and took part in ITV's Dancing On Ice, but was eliminated in week two.
Lauren recently admitted to being "humiliated" after a six-second sex tape was leaked featuring an intimate moment between her and her ex-boyfriend of two years. Lauren said she had no idea the tape had even been filmed, let alone released, and has called for stronger protection for victims of 'revenge porn'.
She published an autobiography in 2013 called Secrets of an Essex Girl.
Lauren is the third TOWIE star to enter CBB, following Mario Falcone and Kirk Norcross.
