Ultimate Big Brother housemate Preston has reportedly been dumped by his American girlfriend Abby Rubin.

The blonde beauty is said to have felt betrayed by the Ordinary Boys singer, after watching him get closer to his ex wife Chantelle Houghton during their time in the house.

In a chat with Nick Bateman yesterday, Preston admitted that he would find it ‘weird’ if Chan hooked up with someone else in the house and added:

“Yeah, I really like her, I think she’s awesome. I’d sort of forgot how cool she is.”

A pal of Preston’s girlfriend told The Daily Star:

“Abby feels ­ cheated. She was never a fan of ­revisiting his time in Big Brother, especially with Chantelle part of the equation.

“She wanted him to settle down into a ­normal life with her, concentrating on projects out of the ­public eye, not being thrown back into it at full speed.”

The pair have been conducting a long distance relationship after Abby’s visa expired and she was forced to return to America.

Her friend added: “It’s ­difficult enough being with someone when they are over the other side of the world, let alone when they are flirting with their ex-wife on ­television in front of an ­audience of millions.”
