Los Angeles, California (CNN) -- The Los Angeles County district attorney filed a misdemeanor drug possession charge against "Tiny" Tameka Cottle, the wife of rapper T.I., Friday.
Cottle, 35, was arrested along with her husband after police found suspected drugs during a West Hollywood traffic stop last month.
She is accused of possessing MDMA, commonly known as ecstasy, according to the court filing.
Drug charges against T.I., whose real name is Clifford Harris, were dropped by prosecutors on Monday.
Harris, 29, must still must report to a federal prison by next Monday to begin serving an 11-month sentence imposed by a judge who ruled his arrest and a subsequent failed drug test violated his probation on a weapons conviction.
Cottle was a successful singer-songwriter with the R&B group Xscape before beginning her relationship with T.I. nine years ago. The couple married earlier this year, soon after he completed a one-year prison term.
She also starred in the BET reality series "Tiny and Toya," which followed her life in Atlanta, Georgia.
