The 26-year-old’s boss admitted the Love Island 2018 star’s frisky ways were a “problem” in his work place, where he works as a stationary salesman.

His boss added that his bubbly personality and hilarious impressions, which have been seen on the ITV2 show, also made him a popular colleague.

Speaking to this week’s OK! Magazine, he revealed: “He does his accents in the office, too!

“Customers love it and they love him. Some of them ring him up on a Monday just to ask him about his weekend.

“And it’s true, when he was single we had a bit of a problem as he was so popular with his co-workers.

“I had to say to him, ‘Can you please stop sleeping with the new women?’”

While he may have a promiscuous past, Jack recently asked 22-year-old barmaid Dani to be his girlfriend.

The pair’s romance hit the rocks in the first week of the show when he admitted he had been a cheat in the past, but it appears the couple are now stronger than ever.

Jack’s boss admitted he thinks the salesman is genuinely “smitten” with Dani, and doesn’t believe he will be interested in anyone else.

He added: “Jack is smitten, Dani is the only girl for him.

“If he really likes someone, there could be ten supermodels behind her and he won’t even look at them.

“He wears his heart on his sleeve.”

After Jack asked Dani to be his girlfriend last week, the Essex beauty went to the Beach Hut to express her thoughts on her new relationship.

She told the camera: “I can’t believe it. I’m actually in shock. I’ve got a boyfriend. Whoopydo!

“I hope my dad’s happy. We’ll still go for sushi because jack don’t like it.

“My dad’s got my first place in my heart. And Jack can have the second.”

After the latest recoupling session, Jack also told Dani he was keen to meet her mum and dad.

He told her: “It’s weird how I’ve got to this stage where I’m even thinking about wanting to meet your mum and dad and making a good impression.

“You are their daughter and I want them to like me because I’ll be spending loads of time with you. So I want them to go, ‘He’s alright’.”

Reassuring her new beau, she told him: “I definitely think they’ll like you, there’s no reason to not like you, is there?”

Love Island continues tonight on ITV at 9pm.
