LONDON: R&B singer Fantasia Barrino has brushed off reports she's dating a married man, insisting she is happy living life as a single girl.

The former American Idol star, 25, was rumoured to be involved with a man named Antwaun Cook, but she is adamant their relationship is strictly platonic.

She tells People magazine, "He's a good friend, and he is not with his wife."

And Barrino admits she is too busy getting her life back on track after a number of financial and health problems to worry about dating.

She adds, "Right now I'm committed to my career. I'm not trying to be in a deep relationship. As hard as I have fought to come back, nothing can stop me."

The singer was forced to take time out of her schedule in 2007 to undergo surgery and remove a hemorrhagic polyp growth on her vocal chords. Barrino then faced financial ruin and almost lost her home in North Carolina in December, 2008 before reaching a deal with local authorities, saving her house from being auctioned off.
