Is there really a split for Heidi Montag and Spencer Pratt?

“I think it’s a joke,” Audrina Patridge told PEOPLE at the MTV Movie Awards in L.A. Sunday. “I don’t believe it. They’re inseparable and in love.”

Besides, Whitney Port also said: “I doubt they’re really broken up. I’m sure they’re still sticking together.”

It also seems that Montag and Pratt are hoping a sham split gives them more tube time.

One source said: “I don’t buy it. I’ve worked with them for too long, and they haven’t been filming, so I think this is a way they think they can get back on the show for the last few episodes.
