Lady Gaga shares a great deal with her fans, but one thing she hasn't expounded much on is her relationship with Vampire Diaries star Taylor Kinney, whom she's been dating for the past year.

However, the pair openly celebrated their 1-year anniversary on Sunday. Along with four friends, they dined at Spiaggia in Chicago, where Kinney is shooting Chicago Fire, an upcoming drama on NBC.

And if there's any doubt that the two are booed up, she posted a picture of them naked— skinnydipping, basically— on her site LittleMonsters.com
