Lady GaGa has been dating Taylor Kinney for awhile now and is apparently head over heels for the guy. So much so that she does not mind spending the night at his place despite the fact he has three roommates, including one who sleeps on a couch. Not exactly what GaGa is probably used to. Kinney, who is on Vampire Diaries, was still with his girlfriend when he started dating GaGa. His now ex-girlfriend found out about the relationship when Kinney pocket dialed her while in kind of an intimate moment with GaGa. Oops.
