Pop superstar Lady GaGa has split from her actor beau Taylor Kinney, according to a U.K. report.

The Poker Face hitmaker has been dating The Chicago Fire star since 2011 after they played lovers in her You And I music video.

However, the relationship between the singer and Kinney has reportedly been on the rocks for several months because of the star's busy workload, and according to editors at Britain's The Sun newspaper, Kinney has called time on the romance because he can no longer deal with her stardom.

A source tells the publication, "Taylor has told her she's married to her career and that he can't deal with dating Gaga the megastar and all her obsessions and alter-egos. He loves the cool, down-to-earth girl but hardly gets to see her.

"Gaga never stops working... She has a whole security team as well as several assistants with her at all times. Out of every month there's maybe just one night out of her and his crazy work schedules that they can be a couple."

Gaga had not commented no the report as Wenn went to press.
