The TOWIE star tweeted a picture of herself on Wednesday (17 June) with laidback tousled locks and what looked like a make-up-free face.
Despite looking super-slim during last month's TOWIE trip to Marbella, it looks like Lauren's got the bikini bod panic just like the rest of us.
She added the caption "Sweaty Betty #gym #selfie #summerbody" as she shared a peek of herself post-workout session.
Sweaty Betty? She's looking pretty flawless to us!
