Lewis hasn't been seen on The Only Way Is Essex since earlier this year. He had fallen out with the boys on the show, after revealing in a game that he had previously kissed both Dan Edgar and Jake Hall's ex-girlfriends Chloe Lewis and Kate Wright in the past.
The boys had been dating Chloe and Kate at the time and didn't appreciate Lewis' comments. Despite making amends with his co-stars, Lewis was hardly seen on the rest of the show's seventeenth series and fans later learned that Lewis had chosen to quit TOWIE.
Opening up about his exit, Lewis revealed in an interview with new! magazine: "It was having a negative effect on how I looked at myself."
"I was struggling mentally," he explained. "So I'd go out drinking and partying a lot to try and forget about it all. That's not really the lifestyle I want to lead."
Lewis added: "I learned so much from being on that show, but I don't think it's a good example of how young girls and boys should live their lives."
Now, Lewis is starring on CBB's current series and on entering the house last week (28 July), Lewis had addressed his TOWIE exit in his VT. He told viewers: "I'm best known for being on TOWIE, I was a bit of an ar*ehole on that show, weren't I? I've outgrown Essex on maturity levels. I'm 26 now. I've got different goals. Different priorities."
On his entrance, Lewis received a slew of support from his TOWIE co-stars, even those he had feuded with in the past, and some predicted that he'd strike up a romance with Geordie Shore's Marnie Simpson.
Proving them right, Lewis has made no secret of how much he likes Marnie and in last night's episode of the show (1 August), we saw Lewis and Marnie kiss for the first time.
They locked lips in the storeroom, before kissing again in full view of their housemates. Gushing about Marnie, Lewis told her: "You're a top drawer bird."
