Things began to turn sour for the co-stars after their third date when Ferne told Liam she wanted to remain friends.
They were soon embroiled in a heated argument argument, where Liam branded Ferne as "jealous", while she called him "bitter".
But, the pair decided to apologise to each other on Sunday night's episode (8 November) and put their fallout behind them.
"Some of the things I said were out of line and I apologise," said Liam. "It was a misunderstanding and we obviously get on with each other and I'd like to be friends with you, if you accept my apology?"
Ferne said: "Obviously, I'm sorry too. It never should have been like that and it's nice that we've sorted things. I guess we never really had a friendship, so now we can actually be friends."
Before hugging, Liam said: "You've always got a friend in Gatsby."
