Taylor Kinney's ex warns Lady Gaga to stay away

Taylor Kinney's ex-girlfriend, Brittany Sackett, has warned Lady Gaga not to trust the actor, claiming she wouldn't be surprised if he had cheated on her.

The Chicago Fire actor’s ex Brittany – who he reportedly cheated on with Lady Gaga in 2011 – believes his infidelities could be the reason behind his shock split from the Poker Face singer.

"He broke my heart because he was dishonest, I just hope he hasn't been dishonest with her as well," Brittany revealed to the Daily Mail.

"At his age it's challenging to change habits that are ingrained and how he functions in relationships.

"It's my belief that a leopard doesn't change its spots."

Lady Gaga broke the news yesterday that her and Taylor were "taking a break" after five years together.

The singer explained their busy careers kept them apart.

“Taylor and I have always believed we are soulmates," the 30-year-old wrote to her Instagram followers. “Just like all couples we have ups and downs, and we have been taking a break."

“We are both ambitious artists, hoping to work through long-distance and complicated schedules to continue the simple love we have always shared.

“Please root us on. We’re just like everybody else and we really love each other.”

The pair met while filming the video for Lady Gaga's song You and I, and got engaged in February 2015.
