LATEST: Teen singer/actress Lindsay Lohan was treated in a Los Angeles hospital on Tuesday (04OCT05) after crashing her Mercedes-Benz convertible into a red van in Beverly Hills.

The MEAN GIRLS star, 19, and a female companion suffered minor injuries following the accident outside The Ivy restaurant, confirmed Los Angeles County sheriff's SERGEANT DIANE HECHT.

The driver of the van suffered moderate injuries and was also treated in hospital, Hecht said.

US TV reporter VICTORIA RECANO, who was filming nearby, insists she's puzzled as to why the young star was speeding through Beverly Hills.

She says, "There was no one following her. She was going pretty fast on Robertson (Boulevard)."

After the accident, Lohan and her passenger ran into an antique store and spent a few minutes trying to calm down, before leaving the building.

Store employee JAVIER RAMIREZ says, "She was very upset. She kept saying, 'Oh my God, oh my God, I can't believe it.'"

The sheriff's department believe the van driver may have been turning in front of the actress' car when the two vehicles collided.

This is Lohan's second car accident this year (05). In May (05), the redhead star suffered minor injuries when she was caught in a collision with photographer GAIO RAMIREZ. The snapper has subsequently charged with assault with a deadly weapon after police believed he drove into Lohan on purpose to cause a photo opportunity.
