According to Us Weekly, the couple grew apart due to their hectic schedule. Cooper, 40, started dating 23-year-old Waterhouse in 2013. The lovebirds were first linked in March 2013 when they were spotted together in Boston.
Bradley Cooper and Suki Waterhouse made their debut as a couple after nine months of dating when the British model-actress was his date to the New York premiere of American Hustle in December 2013.

Suki later accompanied him at the Screen Actors Guild Awards in L.A. Their break up comes as a surprise as last month itself, Suki Waterhouse was snapped at the red carpet of the Oscars where her then boyfriend, Bradley Cooper was nominated for Best Actor for his performance in American Sniper. The couple were accompanied by his mother, Gloria Campano.
They had never been shy to show their affection to each other, but they rarely discussed their relationship in interviews. "I don't talk about my boyfriend because it's boring," Waterhouse once told Elle UK.
Cooper was once married to actress Jennifer Esposito who tied the knot with British model Louis Dowler last year. His other ex Zoe Saldana whom he dated on and off before seeing Waterhouse is also now happily married. She has twin sons with husband Marco Perego.
Both Bradley and Suki's reps have not commented on their split news.
