Lady Gaga

Lady Gaga and her fiancé Taylor Kinney won’t be walking down the aisle together after all.

The bisexual singer/actress and the hunky Vampire Diaries star announced their breakup today.

Gaga, 30, did everything right: she dated Kinney for 5 long years before he popped the question. So what went wrong?

The answer may lie in the way the couple met in 2011.

Kinney, 35, recalls he was smitten by the singer when they met on the set of her music video for “You and I,” where he played her male lead.

“I remember I went up, and we’re rolling, and I kissed her and she didn’t expect it,” Kinney told Watch What Happens: Live host Andy Cohen. “They cut, and she slapped me. And then it was just awkward. And then the next take, I just did it again and then she didn’t slap me. She didn’t slap me then.”

The fact that he was grateful she didn’t hit him again is very telling.

Surely there was someone in his family who whispered to him: “She should never slap you under any circumstance.”
