Rihanna's father Ronald Fenty once advised his superstar daughter to lose weight because he thought she was "too fat," according to reports.

The 24-year-old Barbadian singer has one of the best bodies in the entertainment industry.

But Ronald thought that when she was home for the island's carnival last August, she looked like she had put on a few pounds.

"I actually thought she was a little fat the last time I saw her," he told Heat magazine.

"But when I saw her at this year's Grammys, I thought she was back to her normal size. I used to joke with her, Robyn [Rihanna's first name], you're getting too fat.' But I think she's fine.

"I think she looked excellent, as everyone saw, at the Grammys. She's dieting, she's working out."

Rihanna and her father have had ups and downs in their relationship and reportedly ended their two-year feud in 2010.

Ronald also spoke about his daughter's increasing closeness with ex-boyfriend Chris Brown who beat her up in 2009 while they were still dating.

"Chris is a nice guy and everybody's entitled to make mistakes in their life," he said. "God knows how many I've made. She's her own woman now."

Rihanna has faced criticism for becoming friends with Chris again and she is also reportedly embroiled in a feud with the singer's new girlfriend Karrueche Tran.

The aspiring model reportedly hinted at the friction with a post on her Facebook page alluding to the fact that she was stuck in a messy love triangle the kind of which has rocked the showbiz world before.

"I'm Angeline [sic], you're Jen [Aniston]," she wrote. "C'mon you see where Brad [Pitt] is at."
