The 26-year-old singer - who has been dating the `Vampire Diaries` actor since meeting on the set of her `You and I` music video last year - is reportedly taking a break from the hunk because she doesn`t have time for a relationship during her 110-date Born This Way Ball world tour.
A source told US Weekly: "They are now on a break. She will be touring nonstop until next year and has found she can`t have relationship at the same time."
There`s just no room for anything else. Her work is all-consuming."
Although Gaga appeared smitten with Taylor, friends say the relationship wasn`t destined to last.
The insider explained: "Taylor was all about himself, a typical actor, and didn`t completely get Gaga.
"She loved that she got this guy who everyone thought was hot! But it was never going to last.
"He was never that attentive to her."
Gaga won`t have trouble attracting a new man, previously revealing she is a "cheap date".
She said: "I am a good bowler pre-Budweiser (I love it) and then when the beers start loading up I become worse and worse and worse which is really great for whoever is taking me out because I`m a really cheap date."
