Robert Pattinson, Katy Perry Crash Wedding Rehearsal Of Total Strangers

Robert Pattinson and Katy Perry might be big celebrities, but that doesn't mean they can't crash a wedding every now and then.

On Sunday, Pattinson and Perry crashed the wedding rehearsal of a couple getting ready to walk down the aisle at the luxurious San Ysidro Ranch hotel in Montecito, Calif., a guest told People magazine.

"Katy and Rob were just sitting next to each other watching the wedding rehearsal in the main courtyard area," Stephanie Sands told the magazine. "They were dressed very casually. She was wearing a hoodie and big sunglasses. There was no PDA between them and no body language that showed they were dating. They just sat together and watched."

"They were not affiliated with the wedding party and were not seen mingling with guests," Sands, who has "no idea" why they were there, added.

Sands later tweeted that the bride-to-be, her personal friend, was the one who first spotted the "Twilight" heartthrob and the pop singer together at the rehearsal.

Rumors are already swirling Pattinson and Perry might be dating, but this is not the first time they have been linked. Since his split from Kristen Stewart earlier this month, tabloids claimed the 27-year-old actor was spotted "getting cozy" with the "Teenage Dream" singer. Gossip Cop sources quashed the rumor as "pathetic" and said Pattinson and Perry are just friends, but E! News sources say she might have played a role in his breakup with Stewart.

Meanwhile, Us Weekly claims Perry might be getting back with John Mayer after breaking things off in March. The crooner attended Perry's Memorial Day barbecue bash at her new Hollywood Hills home on Monday, the magazine reports. The two were supposedly "flirty" and seemed "back together-ish."
