Fantasia BarrinoFantasia Barrino, the winner of American Idol in 2004, and nominee of eight Grammy awards, has been accused of having an affair with a married man.

Paula Cook, a North Carolina woman who is now separated from her husband, has filed divorce related documents in Mecklenburg County District Court.  In them, she alleges the singer began the affair in August of 2009 after meeting her husband, Antwaun Cook, in a Charlotte T-Mobile store.

The allegations include that Barrino provided an expensive lifestyle for Cook over the course of their relationship, including flying him around the world. The documents also suggest that some sexual activity was recorded by the couple.

Barrino has been seen with a tattoo on her left shoulder that simply says Cook, and he is said to have a similar one in the same place.

Both Barrino and her record label declined comment on the matter.

The documents suggest that while she tried to salvage her marriage, Paula Cook was unaware of the notorious relationship her husband was involved in.

She is seeking custody of their two children, alimony and other monetary support, and ownership of the marital home.
