Amanda Bynes has reportedly been involved in a third hit-and-run incident.

The Hairspray actress is at the center of a police investigation after a woman reported her for allegedly bumping into the rear end of her vehicle then driving off after refusing to exchange insurance information in the San Fernando Valley on Sunday.

The woman, known only as Kisa, told TMZ that Amanda "looked like a hot mess" and claims she didn't immediately recognize the former child star when her Toyota Corolla was struck by the actress' black BMW on Ventura Boulevard. Kisa added that Amanda "seemed nervous" when she suggested they swap information and says the 26-year-old star attempted to play down the "significant" damage before returning to her vehicle and driving off. Kisa then called police, who filed a hit-and-run report.

The alleged incident is the latest in a string of vehicular problems for the troubled actress, which has included two other allegations of leaving the scene of an accident, and one of driving under the influence (DUI).
