Tallia Storm and Love Island's so-called Muggy Mike have been getting close on Celebs Go Dating.
The pair are said to have ditched their dates with members of the public in favour of one another.
The Daily Mail reports that the couple were getting "cosy" during filming of the show's finale at Cape Verde, to air at the end of the month.
"There is clearly something going on behind the scenes between Tallia and ‘Muggy’ Mike," an insider said. "They were cosy on many occasions, sneaking off to the beach together and even spotted sitting together on the long haul flight home from Cape Verde."
The insider added: "He seemed very protective of her and not his usual Muggy self."
However Tallia has insisted: "We're just friends"
And Mike remarked: "If I was going to crack on with her, I'd have done it on screen. I wouldn't keep it a secret."
It's wouldn't be the first time two of Celebs Go Dating's stars have got with one another.
However neither relationship lasted, both ending on rather messy terms.
Meanwhile, Tallia has spoke about her ex, Brooklyn Beckham.
In last night's show, dating agent Nadia Essex asked: "Talk us through your previous boyfriends."
"I've only had one, which did not end well, let's just put it that way.... I knew this was gonna come about I don't want to talk about him," Tallia replies.
Nadia told cameras: "There's a huge elephant in the room, an if Tallia can't be honest, I'll call her out Simple."
Nadia demanded: "Tell us about Brooklyn Beckham."
"I had the biggest crush, I got butterflies... but I was too young," Tallia said as she opened up.
"I want a man... but I'm rusty. I don't know how to be flirty!" Tallia added.
Rounding off the cast are Love Island's Muggy Mike, TOWIE's Gemma Collins and MiC's Sam Thompson.
Celebs Go Dating 2018 continues tonight at 9PM.
And as opposed to airing Monday-Friday each night, the latest series will now air Sunday-Thursday every evening.
