Lady Gaga and boyfriend Taylor Kinney have reportedly split up.
The Sun reported that the couple's relationship came to an end because actor Taylor got fed up with Bad Romance singer Gaga's busy workload and life, which meant they were rarely able to spend time together.
A source said: "Taylor has told her she's married to her career and 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 writes songs in the shower and dreams up new outfits in her sleep.
"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."
Things might not be over for good though, as Gaga, 27, is apparently hoping to meet up with Chicago Fire star Taylor, 32, to "talk things through".
But the source said: " Taylor told her they need time apart and it's looking as if this might lead to a permanent split."
Taylor and Gaga started dating in 2011, after the singer chose the actor to play her lover in the video for hit single You And I.
