Is Lady Gaga back with her ex?

She’s always kept us guessing, swearing off men, announcing she’s bisexual and cavorting with beautiful women on stage and off. But now it seems Lady Gaga is back with the boys – indeed, she’s returned to former flame Luc Carl.

The ‘Alejandro’ singer has been spotted hanging out with her ex-boyfriend on several occasions recently and insiders insist they’re heading for a reconciliation. We’re told that while Gaga split with Luc before she rose to superstardom, her Ladyness (24) never quite got over him.

“Gaga’s first album is entirely about their relationship,” says a close source. “Her new song ‘You and I’ is about how they got back together. They’ve been in love for a while.”

But while she may be getting loved up, Gaga has drawn hate from Beatles fans after she was photographed playing the piano of late legend John Lennon in a skimpy outfit.

The picture, which appeared on the Twitter page of John’s son Sean Lennon, was removed after Beatle-maniacs objected. But Sean moans, “Pianos are meant to be played. Why is everyone so uptight? He gave that piano to my mother for her birthday – it is hers. Secondly, he was not uptight the way you seem to be.”
