Gemma has openly said that she's there to make "good TV" and "good entertainment", and Tommy believes Gemma is doing a pretty decent job of it by getting lots of airtime.
Speaking about his former co-star at the National Television Awards held at London's O2 Arena, Tommy told Reveal: "I've been away for the last 10 days, so I've only caught up with the last two days of it. What can I say is, GC is in the house! Not Gemma Collins, but GC!
"There's some real diva sh*t going on. You either go in the house and lay in bed, or you go in there, lay in bed like she has and get involved, so you can have 12 hours sleep and wake up and start on someone and get on screen."
On Wednesday night's episode, Gemma told fellow housemate John Partridge the difference between Gemma and GC, with Gemma being her sensitive, sweet side, and GC her fierce diva alter-ego."
Tommy added. "But it's all good. I haven't seen too much of Gemma's arguments but there's some lunatics in the house by the looks of it!"
Meanwhile, Tommy's girlfriend, Georgia Kousoulou, said: "Gemma's a natural [at playing up to the cameras]. She finds it easy. It makes good TV, doesn't it?"
