A source told E! online that the split was Rihanna’s choice, as the 25-year-old singer wants to focus on her business and career opportunities including a perfume and clothing launch, the Sun reported.
News of the alleged split comes after Brown was feared to be cheating on the Barbadian artist again as he was spotted hanging out with a blonde waitress in New York.
Rihanna, who is in the midst of her epic Diamonds tour, was recently spotted sans Brown at a basketball game in LA. It was in February, Rihanna and her volatile boyfriend had confirmed that they were back together.
The confirmation came after the couple fuelled speculation about their reunion with a series of Twitter images, which showed them being close together.
Rihanna had given Brown, 23, a second chance despite fears among fans that he could mistreat her again after he battered her in a pre-Grammy row in 2009.
