Lady Gaga, Taylor Kinney split?

London: Pop sensation Lady Gaga has reportedly parted ways with actor boyfriend Taylor Kinney.

The `Applause` hitmaker has allegedly been dumped by Kinney, whom she has been dating since 2011, after he struggled to deal with her demanding work schedule, reported Femalefirst.

"Taylor has told her she`s married to her career and that he can`t deal with dating Gaga the mega-star 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," a source said.

The 27-year-old singer has been struck with a string of bad luck this year after undergoing debilitating hip surgery in February, having good friends turn their backs on her, and losing her pet dog Alice last week.
