The reality TV lovebirds, who went public with their romance in Las Vegas, have been spending all their time together recently and Lucy stayed the night at Tom's in the last episode of the ITV2 show.
And tomorrow (Oct 20), it becomes clear that the pair are as inseparable as ever - especially in the bedroom!
While not everyone believes Lucy's romance with Tom is real, she seems to be trying hard to put her relationship with ex-fiancé Mario Falcone behind her.
Scenes show Lucy and Tom chatting in bed, with his hand affectionately laid on her leg, and her gazing adoring at her new beau.
Meanwhile, Sam Faiers and Joey Essex have a long-needed heart-to-heart about their relationship.
While both have moved on, the couple - who got engaged in front of the TOWIE cameras earlier this year - definitely need closure.
Joey recently told us that he and Sam still care about each other, and "still have love there".
In other scenes, Sam has a chat with best friend Ferne McCann about her recent heartbreak over ex-boyfriend Charlie Sims, Bobby Norris moves into Gemma Collins' flat with help from Lockie, and Chloe Sims, Lauren Pope and Frankie Essex talk breast reductions on the fruit aisle... Natch!
