Celebrity Big Brother contestant Jonas 'Basshunter' Altberg has been dating 22-year-old model Olivia Maria for more than a year, it's been reported.

The revelation comes despite the fact he has been flirting with fellow housemate Katia Ivanova, referring to her as his “soul mate”.

Olivia, who confirmed the relationship, told The Sun: “I talked to him the day before. We are dating. I can’t mention Katia. I don’t want to comment.”

Friends told the paper that they are worried about Olivia, who Tourette’s sufferer Jonas penned his October hit Every Morning for.

A source said: “All their friends are very worried about the effect on Olivia. They have been together ages and she is very much in love with him.

“But unfortunately he doesn’t treat her right. They have split up a number of times in the past and it’s usually over other girls.

“Olivia says she doesn’t mind but we can all tell it’s upsetting her. She didn’t think he would pretend she didn’t exist to this extent.

“For a man with Tourette’s he’s certainly good at keeping some things to himself.”

The source added: “Olivia wants to talk to Jonas. When they’re together he’s a gentleman. But when they’re apart it’s like he forgets her.

“She knows he’s trying to win the show, but she is feeling hurt.”

Apart from calling 21-year-old Katia his soul mate, Jonas, 25, has also shared a bed with her, frolicked in the snow, and confided that he used to pleasure himself 25 times a day.
