Lady GaGa & Luc Carl "Totally Back Together"
The Poker Face star is said to be back in the arms of her ex-boyfriend...
Speaking of the tune, GaGa stated: "There is not one song on any of my records that wasn't written by me."
"I think when you write your own music you find ways to reinvent [the songs] emotionally through yourself and performance so that they are different every night and that song you know, sometimes it's about the guys and sometimes its about the fans."
The 25-year old added: "I get emotional each time I sing that song."
