Lady Gaga and Taylor Kinney: The PDA-Fest!

Lady Gaga made some morose comments about her past relationships the other day, but it looks like her budding romance with Taylor Kinney is in full swing.

The singer and her buzzed-about new beau were spotted sharing some backstage PDA at the KIIS-FM Jingle Ball at L.A.'s Nokia Theatre, according to People.

The two kept their hands to themselves in public, but they were spotted embracing in the privacy of the hallway backstage. Looks like Gaga's got a keeper ...

The couple met on the set of her "You and I" music video in Nebraska, and - despite her claims that it's not serious - they have been inseparable ever since.

While some of the actor's Vampire Diaries co-stars were also at the show, and even walked the red carpet, he stuck by Gaga for her headlining performance.

Onlookers later spotted the two holding hands and acting like a couple.

A cute couple, albeit an unlikely one, to say the least ...
