These two young stars costarred in one of the biggest movies of the year and everyone speculated that they had an affair. But that’s only half right. The female lead DID have an on set fling – but not with her costar – with her costar’s GIRLFRIEND when she came to visit! Ironically, the girlfriend is also a major star but she wouldn’t let her hunky boyfriend join in the fun. Both women are bisexual and he’s straight.
