Lady Gaga has said sorry to her boyfriend after telling fans at a Joe Biden rally that she loved her ex "so much"

She said: "Anyone here from Lancaster?

"Well, I was engaged to a man from Lancaster, Pennsylvania. I know, I know, it didn’t work out. I loved him so much, it just did not work out. But I still love my Pennsylvania guy. I love Joe! So Joe’s my new Pennsylvania guy."

But in between performing 'You and I', Gaga stopped and said sorry to her current boyfriend Michael Polansky for speaking about Taylor - who she dated from 2011 to 2016 - and dec lared her love to the tech entrepreneur.

She said: "To my boyfriend here tonight, I’m sorry I had to do this whole, 'Pennsylvania, I dated a guy here' thing.

"I love you so much, but it’s true."

Meanwhile, at a rally in Biden's hometown of Scranton, Pennsylvania, on Monday, his rival and current president Donald Trump hit out at Gaga for supporting the 77-year-old former vice-president.

Addressing the crowd, Trump said: "Now he’s got Lady Gaga.

"I could tell you plenty of stories - I could tell you stories about Lady Gaga, I know a lot of stories."

And he hit out at John Bon Jovi.

Trump said: "Every time I see him he kisses my a**. 'Oh, Mr President.'

"He'll get something out of it, just like everyone is.

"By the way, we draw much bigger crowds than these people.

"They got Beyonce, and they got Jay-Z."
