Rapper Foxy Brown is threatening legal action against gossip bloggers amid false reports suggesting she has been badmouthing Jay Z by allegedly accusing him of engaging in gay sex and taking her virginity when she was just 15.

The Candy hitmaker was rumoured to have dished on her former mentor's dirty secrets at a recent baby shower she attended, supposedly revealing all about how Jay Z bedded her when he was 27 and she was still a teen.

The online reports, which first appeared on MediaTakeOut.com, also suggested that Brown had put the Empire State of Mind superstar on blast at the bash for giving her a sexually transmitted disease, as well as claiming that he had enjoyed a secret affair with former New York Knicks basketball player Larry Johnson.

However, Brown insists the blogs are full of lies and she is planning to sue to clear her name.

She tells Tmz.com, "The atrociousness of this story sickened me to my stomach. Any and everyone involved will be contacted by my attorney.

"In all my years in the music industry, these are the most disgusting and disrespectful allegations I've ever experienced. This fictitious story... with No audio, visual or written interview, clearly was concocted with malicious intent.

"Jay has only been wonderful to me and my family, a great friend throughout all the years I've known him and we had nothing but great success as a team. Beyonce, his wife, has always been gracious and sweet to me... I will NoT let any undercover hater create discord and disrespect my name and reputation.

"This disrespect will NoT be tolerated."
