Lady Gaga reportedly split from Taylor Kinney because she wanted "more adoration" from the actor.
The Poker Face singer had been dating the Shameless star for about ten months but it has been claimed they have now broken up.
A source from the set of Shameless believes Taylor's laidback personality may have contributed to the split. He was apparently too relaxed about her A-list status.
"But after a while, I think she wanted a little more from him — a bit more adoration, if you follow me," a source told the Chicago Sun-Times.
However, other insiders believe it came down to the pop sensation's busy schedule.
The singer's plate is full with her demanding 110-date world tour.
"The two most important things are her career and her immediate family," another source said.
"There's not much room for anything else, with the exception of her charity work."
The revelations follow reports Taylor was too self-involved for the star. He was said to have trouble understanding the Bad Romance star.
"Taylor was all about himself, a typical actor, and didn't completely get Gaga," an insider told Us Weekly.
"She loved that she got this guy who everyone thought was hot! But it was never going to last."
