In a new preview clip, Tom is seen turning on the charm while at a party with Fran - and poor Diags can only look on from afar.
Tom tells the new brunette: "We get on so well, we spend a lot of time together and we had fun in Ibiza together, didn't we?" Fran replies: "We did, it was good fun."
Smiling, Tom adds: "So I was thinking, we should go for a drink." Agreeing, Fran says: "Yeah, let's go."
Fran then dissolves into a fit of giggles, as Tom tells her: "You're going all giddy." Looking coy, she asks: "Am I? You make me nervous Tom, that's why."
Prior to their chat, Diags is shown discussing Fran with James 'Arg' Argent and Lewis Bloor.
"Is there a girl we've met in the past three years that you get along with as half as well as with Fran?" Lewis asks him. Diags replies: "No..."
Sticking the boot in further, Arg tells him: "I've got to say, I do feel sorry for you mate as it's never just simple, is it?"
The clip finishes with Tom kissing Fran on the lips as Diags looks on awkwardly. Oh dear!
Meanwhile, also in tonight's TOWIE, Ferne McCann gets a shock when the mysterious Frank Major pitches up at Gemma Collins' party.
