Drake counters a lawsuit claiming that he owes a woman money for use of her voice on “Marvin’s Room.”

According to an exclusive story by The Hollywood Reporter, a woman claiming to be Drake’s ex-girlfriend and the inspiration for “Marvin’s Room” is suing the YMCMB rapper for co-writing royalties on the song.

Ericka Lee, who is credited in the liner notes of “Marvin’s Room” as a vocalist under the name “Syren Lyric Muse,” believes she is entitled to a larger share of the song’s royalties. Lee filed her initial claim in July of 2011, and was met by a counterclaim from Cash Money/Universal Records roughly six weeks later. According to Lee’s suit, she believes her

“contribution is highly significant to the overall work.”

“Drake allegedly agreed to work with Lee on ‘Marvin’s Room’ and split the proceeds,” writes Eriq Gardner of The Hollywood Reporter. “Lee says she was asked to record the song’s ‘hook’ as well as the opening monologue that would serve as the thematic framework for a song about Drake’s yearning for an ex-girlfriend and how his fame interfered with his love life.”

Lee also claims she was offered a $50,000 payment along with 4-5% of the song’s royalties after threatening Drake with legal action prior to filing her lawsuit. “Marvin’s Room” peaked at the number 21 spot on Billboard magazine’s Hot 100 singles chart.
