Now, he's lost his greatest claim to fame. He and Lady Gaga have split over "creative differences," according to Hollywood Reporter's sources and Showbiz411. One person told Hollywood Reporter that Carter feels "sad" but "liberated" by the breakup. He's credited with helping Lady Gaga sell 20 million albums but recently, his plate has become extremely full.
Carter also manages John Legend and Lindsey Stirling. He's in the middle of raising a $75 - 100 million investment fund. Lady Gaga's new album, ARTPOP, will be released on November 11.
