Charlotte arrived at the Thai villa as Gaz Beadle's ex-girlfriend in episode two, but Bear's the one working his charms on her in next week's third episode.
A preview clip shows Bear lying in bed and playing with Charlotte's hair as he tells her: "We could have little bear cubs. That's all I want. Little Bear cubs with someone pretty."
He then tells the camera: "I want to f**k her all night."
Char, meanwhile, comments: "We are just so the same. It's f**king weird."
This year's Ex On The Beach is an all-star series featuring memorable contestants from previous years. Bear, who has been causing drama in the CBB house this summer, was initially on series three.
He first tried his luck with Chloe Goodman, but she wasn't interested at all. So he booted her from the show when the Tablet of Terror gave him the power to eliminate one contestant. He's also had a cheeky snog with ex Kayleigh Morris on the first episode but any hopes of something else seem to be dashed after Chloe told Kayleigh that Bear had called her a dog behind her back.
Charlotte, meanwhile, was a hit with the boys when she rocked up to the beach this week. Jordan Davies was particularly interested, flirting up a storm when he took her on a date, but sadly for him, Char said she was keeping her options open when it came to the men of the house.
Ex on the Beach continues on Tuesday 30th August at 10pm, only on MTV.
