For those losing sleep over Speidi’s separation, the joke may be on you. Several of Heidi Montag and Spencer Pratt’s Hills castmates say the duo’s breakup is just another one of their publicity stunts.
“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.”
Also questioning the validity of the split is Hills-turned-City gal Whitney Port. “I doubt they’re really broken up,” she said. “I’m sure they’re still sticking together.”
