While Jennifer Aniston denies rumors of any romantic relationship with actor Orlando Bloom, friends of the thirty-nine year old actress claim not only is the former Friends star dating the Brit, she’s been doing so behind the back of his Victoria’s Secret supermodel GF, Miranda Kerr.

“Orlando is so busted,” an Aniston insider tells Star Magazine. “He thought he could cheat on his girlfriend and not get caught — with Jen of all people. But the news made its way back to Miranda in no time. What was he thinking?”

Jen and Orlando were spied flirting at a recent charity bash held by celebrity hairdresser Ken Paves:

“Jen started following him around, jealously making sure no other woman grabbed too much of his attention,” a spywitness says. “Once Orlando worked out what was going on he started to ferociously hit on Jen. Their chemistry was undeniable.”

“They got very touchy-feely and they didn’t care at all who saw them”
