VIDEO : Rihanna Says Thought She Could Be Chris Brown's 'Guardian Angel'

Grammy-winning R&B singer Rihanna said she once felt she was strong enough to take back boyfriend Chris Brown after he famously assaulted her in 2009, but finally realized she had been stupid to think that way.
"I was very protective of him. I felt that people didn?t understand him," she told Vanity Fair magazine in a cover story for the November issue.
Explaining why she took him back after he left her bloodied on the eve of the Grammy awards, Rihanna, 27, said she thought "Maybe I?m one of those people built to handle ... this.
"Maybe I?m the person who's almost the guardian angel to this person, to be there when they?re not strong enough" and to be able to "say the right thing."
