Lady Gaga back with boyfriend Luc Carl

“They had a little fight. I think the break-up lasted a week or two. But they are totally back together now,” a source said.

Gaga wrote the song ‘You and I’,which features on her global chart-topping album ‘Born This Way’,about 30-year-old Luc and admitted in the wake of the break-up performing the track made her emotional.

“There is not one song on any of my records that wasn’t written by me,and 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 guy and sometimes it’s about the fans,” she said.
