Taylor Kinney stopped by Watch What Happens Live on Wednesday night and ended up revealing a hilarious detail about the beginning stages of his romance with Lady Gaga [1]. The couple, who got engaged in February, first met on the set of her "Yoü and I" music video in 2011. "I remember I went up, and we're rolling, and I kissed her and she didn't expect it," Taylor explained. "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."

The cute confession comes shortly after Taylor admitted that he would love to work with his fiancée again [2]. Watch Taylor gush about Gaga above, and then check out 12 of the singer's moments that blew us away this year [3].
