Jack Fincham and new girlfriend Frankie Sims film their first reality show as a couple – Ex In The City S2

JACK Fincham and his new girlfriend Frankie Sims have filmed their first reality show as a couple.

Ex In The City series two will hit our screens later this year - and viewers have been warned to expect "fireworks".

Essex pair Jack and Frankie - who claim to have "insane chemistry" - had their relationship put to the test when they came face to face with their exes on the MTV show.

A source told The Sun: "Jack and Frankie signed up for ex in the city - and were both horrified when some surprise exes turned up.

"They're actually a really strong couple, so they made it through the show - but viewers should expect fireworks onscreen."

Jack signed up to do the show last year, but it was cancelled amid the pandemic.

Since then he's found love with Frankie - just weeks after his split from her Towie co-star Chloe Brockett.

But 26-year-old Frankie denies there was an "overlap" and told The Sun they rekindled their romance three years after their first fling.

Jack's other exes include Dani Dyer, Ellie Jones, Connie O'Hara and Laura Anderson.

Meanwhile Frankie had an upsetting split from her ex-boyfriend Harry Lee from Towie.

"We’ve got history," Frankie exclusively told us after confirming her relationship with Jack last month.

"We met in 2019 and we had a fling but it didn’t work out because I lived up North and he lived down here.

"He came back into my life not long ago. We just rekindled instantly, we just got together instantly.

“Jack’s got something about him where I’m just like ‘yeah I like that’, we’ve got insane chemistry.

"I don’t have chemistry with a lot of people, I hardly ever get chemistry with anyone.”

The Essex beauty explained that she wanted to keep their romance under wraps at first.

"I like that people didn’t know, not everyone can know every single romance that you had in the past," she said.

Frankie said that her new man is currently ticking all her boxes and he's exactly what she's been looking for.

"He’s lovely, he’s funny, that’s all I ever wanted just someone that I can bounce off of and have a laugh with," she said.

"That’s all I was looking for in life. He’s walked into my life and we have an amazing time together."
