The Only Way Is Essex original made her debut way back in series one, episode one, but left the programme in series six to pursue other opportunities. She's returning now, for series 19, making her hugely anticipated debut on Sunday night's episode.
Ahead of the show, she's been answering questions on the TOWIE official Twitter account, including what her most embarrassing TOWIE memory is.
Ooh, good question!
Lauren answered: "I've had about 300! I look back and cringe; the make-up, loads of things. And at the beginning I think we did loads of things and showed body parts we shouldn't have shown! I ain't even gonna say, I'm that embarrassed!"
The 29-year-old had no such hesitation when it came to naming what TOWIE star she'd like to return next: "Joey Essex! He's hilarious."
She was also asked to play Snog Marry Avoid with co-stars James 'Arg' Argent, James 'Lockie' Lock and Dan Edgar. Awkward!
"This is horrible!" laughed Lauren.
"I would marry Arg because Arg is Arg and I've known him for years. I would snog Lockie but actually wouldn't, I just have to answer the question! And I would dump Dan." Poor ol' Dan!
Watch Lauren's Q&A below:
Tune into TOWIE on Sunday at 10pm for her return!
