Lady Gaga's going public!

In a series of just-released photos taken December 11, the 25-year-old songstress is finally acknowledging her romance with Vampire Diaries star Taylor Kinney.

Clad in a black mini dress and lace-up stiletto boots, the singer -- who first met Kinney on the set of her "You and I" music video when he starred as her love interest and makeout partner -- casually slung her arm over her boyfriend's shoulder as they strolled along a California beach.

While the pair sure appear cozy in the new pics, a source close to Gaga tells Us Weekly they're not super serious.

"They're hooking up and getting to know each other," explains the insider. "Gaga can't be too committed because she works 24/7. But she thinks he's supercute!"
