The reality stars continued filming for TOWIE's 11th series and kept each other company on Saturday (15 February) while relaxing in the steamy hot tub.
Tom and Lauren, who dated on the show in 2012, looked cosy as they snuggled up to one another for a close-up photo.
Pulling a facial expression, Tom said: "Grrrr @LaurenPope."
Posting another photo of herself on Twitter, Lauren said: "Filming for @OnlyWayIsEssex yesterday in the sickest house! #towie #bikini #jacuzzi."
In the snap, Lauren showed off her model credentials as she posed against a glass backdrop, wearing an electric blue halterneck bikini and a dressing gown draped off her shoulder. Sultry!
Tom also posted an Instagram video of the pair listening to music, and even zoomed in on Lauren's assets! (Watch video below).
The cast of TOWIE kicked off filming last week and it's gearing up to be an eventful series so far. Pregnant Billie Faiers celebrated her baby shower with her co-stars, meanwhile Mario Falcone partied with his co-stars for his birthday party on Saturday.
Elsewhere, we've also seen Gemma Collins and Elliott Wright endure some intense workouts in a park.
TOWIE series 11 airs on Sunday 23 February at 10pm on ITV2.
