Tommy's been accused of being unfaithful to girlfriend Georgia Kousoulou in Newcastle before Christmas, but he's strongly denied the allegation.
On Sunday night's episode of the ITVBe show, we'll see Lockie chatting with Tommy and giving him guidance on how to move things on with Georgia.
Meanwhile, we'll see Lockie's girlfriend Danielle Armstrong having a heart to heart with Georgia about her own experience as she's faced a similar situation in the past, with Lockie accused of cheating on her.
Danielle will question Georgia on whether she truly believes Tommy or not…
So far, Georgia has stood behind her man and said she believes him.
She told the official TOWIE website she didn't believe the cheating claims, which came from Diags. She spoke about the last episode, in which Diags and girlfriend Fran Parman had a row with Tommy and Georgia at the St. Patrick's Day party.
"If you had something to prove, you'd want to prove me wrong. You'd say your boyfriend did cheat, here's the evidence... they're not doing that. I feel like they've made it up, spread it and now they've realised they look bad, they've walked off because they have sh*t themselves."
TOWIE continues Sunday 22 March at 10pm on ITVBe.
