Chinga Chang Records boss Daniel Herman recently revealed the embattled 27-year-old actress has been working on her music debut, and suggested the Gone Till November hitmaker could be brought on board to advise her.
However, the former Fugees star's management team has now distanced Jean from the story, telling Tmz.com their client has no plans to collaborate with Bynes.
They also insist the rapper has never even spoken to the Hairspray star.
Bynes has been a tabloid staple in recent months - after a number of driving dramas last year (12), she is now facing charges for marijuana possession after cops arrested her at her New York City apartment in May (13).
She also faces a charge of reckless endangerment for allegedly throwing a bong out of the window as officers raided her home following reports she had been smoking pot in the building's lobby.
