Nicholson's Baby Mama Busted

Rebecca Broussard, the mother of Jack Nicholson's two youngest children, was arrested Sunday afternoon on charges of felony DUI. She was booked into Valley Jail in Van Nuys, Calif. late Sunday night and released on $100,000 early Monday morning.

Sources tell TMZ her current husband, Dennis, was a passenger in the vehicle and suffered a broken arm. Broussard, who was arrested under her former married name of Rebecca Kelly, is due back in court September 17.

Broussard and Nicholson have a daughter, Lorraine, 17, and a son, Raymond, 15.

TMZ could not locate a rep for Broussard.
