Lady Gaga & Taylor Kinney’s Open Relationship?

Lady Gaga has an “open” relationship with Vampire Diaries hottie Taylor Kinney, according to a new report.

“Gaga told him they can both sleep with other people as long as it’s just sex,” a source claims to Star magazine. “Taylor didn’t know how to react. He doesn’t want an open relatioship.”

The magazine says that Gaga is “insecure and paranoid that Taylor is going to cheat on her — so she decided that if she allows it, he won’t, because it takes away from the thrill.”

But Taylor’s not having it: Says the source: “It’s pushing him away.”
