A rep for the 'Boy Is Mine' singer confirmed the split to Us Weekly but said the former couple remain amicable: "The engagement is off but the friendship is still on."
The spokesperson said the pair are now taking some time to "reevaluate" their relationship, suggesting a permanent break might not be on the cards.
Brandy, 35, and Ryan became engaged over Christmas 2012, with Brandy showing off her beautiful engagement ring shortly afterwards while holiday in Hawaii with her new fiancé.
The star had hinted earlier that year that she was hoping for a proposal but not pressuring Ryan, telling Sister2Sister magazine: "I'm going to be patient and let it happen and just let it be."
Brandy has a twelve-year-old daughter Sy'rai from a previous relationship.
