Star of The Hills, Audrina Patridge, says she and the cast think Heidi Montag and Spencer Pratt's divorce is a publicity stunt.
The 25-year-old is in the UK to chat about the MTV reality show which comes to an end in a few weeks.
The couple, who are also known as Speidi, have not been seen on screen for a few weeks and Audrina says they have pretty much locked themselves away:
"I think they're still together at the moment. They just disappeared. I don't know what they do. None of us see them. None of us talk to them. They never go out of their house. So none of us really know what they're doing."
And when Audrina was asked if Heidi and Spencer's divorce was a publicity stunt, she replied: "We all think so."
The TV beauty also spoke of Heidi's plastic surgery. The 23-year-old recently had ten procedures in one day and Audrina remained diplomatic about her ex-friend's new look:
"That was her decision and she was set on it. She wasn't going to let anybody change her mind. She's happier with herself... that's what she says."
