Has Lady Gaga moved on from her split with Christian Carino?

The Joanne singer made waves this weekend when she kissed a trumpet player onstage at her Las Vegas residency show Lady Gaga Jazz & Piano.

The trumpet player in question is Brian Newman, who happens to be a married man.

In a video posted to Twitter, Gaga, 33, can be seen holding hands with Newman, 38, as she serenades him.

She sings, 'Darling, kiss me.'

The two of them then share a gentle smooch on the lips.

Although he's married, it appears to just be an innocent part of the show.

A source told Us Weekly: 'There is nothing to see here. Gaga is a performer, and it was a playful, harmless part of her act.

'She and Brian have had an incredible friendship for years and see each other as family.'

Gaga has been single since her split with ex-fiance Christian Carino, 50, in February.

Many fans have been quick to assume the breakup was a result of her undeniable chemistry with Bradley Cooper, 44, in the Oscar-winning remake of A Star Is Born.

On the contrary, a source told People: “It just didn’t work out. Relationships sometimes end. There’s no long dramatic story.”

Meanwhile, Cooper is recently single as well, adding to the rumour mill.

In this case, it appears that the film may have had something to do with his split from model Irina Shayk, 33.

A source close to the couple told People: 'Bradley was emotionally absent during the long time filming.

'They tried to save the relationship but it had changed.'
