GAGA MOVES ON FROM BRADLEY!

The world thought she was mixing business with pleasure by striking up an off-screen romance with her A Star Is Born co-star Bradley Cooper, but it looks like Lady Gaga was working elsewhere on a new romance!

During a brunch date at Granville eatery in LA, the singer, 33, was seen kissing sound engineer Dan Horton, who has worked for her since November last year.

“She seemed very happy when interacting with [Dan],” says a fellow diner.

But no stranger to controversy, it seems Gaga’s new fling has already caught the attention of Dan’s ex-wife Autumn Guzzardi. The actress, who only divorced Dan, 37, last year, posted a picture of herself on Instagram with the caption, “Poker face” – the title of one of Gaga’s early hits.
