Julius Cowdrey and Harry Baron fight over Ella Willis in tonight's Made In Chelsea.
And here's a first look clip.
Having cheated on Ella, a sheepish Julius is keen to make amends - but with Ella's ex Harry Baron back in town, is he too late?
"Maybe now I should just swoop in there," Harry tells Sam after hearing of Julius' actions.
"It's not going to happen on my watch," declares Julius as he chats with some of the girls.
Later the boys face off over Ella at a party.
"You cant deny we do have fun," Harry tells Ella.
She replies: "It is fun but I don't want to flirt with you.
"But you did," he claims, "You do have a guard up with me and I feel once you let that guard down, things will be different.
"I just don't think Julius is your type , the chemistry between you guys seems really unnatural."
Julius reacts: "You're an incredibly arrogant man and I have never met anything like it in my life."
Elsewhere on this evening's show, Josh Patterson and Binky Felstead face becoming parents, thanks to Ollie Locke.
Keen to help JP prepare for fatherhood, Ollie decides to take matters into his own hands and give him a crash course on childbirth.
"Do you have a birthing plan?" he asks in a chat with JP and Binky.
"I don't even know what that is," admits JP.
JP and Ollie then go on to watch a birthing video together, which it appears they soon regret.
JP reacts: "Poor Binky, what have I done to her?!"
Meanwhile, all is not well in Frankie and Jamie's relationship as it's revealed that they have both cheated on one another.
Made In Chelsea 2017 airs tonight at 9PM on E4.
