Jesse Grant/Getty Images, Rebecca Sapp/Getty ImagesSpeedy's disco stick is no longer Lady Gaga's for the riding.
The mono-monikered entrepreneur broke up with his hitmaker girlfriend of three months Wednesday after a photo of her snogging another fella made it into the U.K.'s Sun tabloid, a source close to the ex-couple exclusively tells E! News.
The ill-advised makeout session occurred at the restaurant Balans in London's Soho district, where Gaga trotted her 20-person entourage following her man-straddling gig at Brixton Academy.
"He was so disappointed, but he's not into cheaters," our source said of Speedy. "It was hard enough for them to be in a long-distance relationship, but then this came out and it was over for him."
The 31-year-old Los Angeleno had put business on hold to accompany Gaga on tour. The previously happy duo, who met on the set of her "Love Game" video, also vacationed last month in Hawaii, where they were photographed smooching on the beach.
Maybe Lady Gaga thinks you're just supposed to start kissing anyone when there's a camera around.
A rep for the singer didn't immediately respond to a request for comment.
