Lindsay Lohan in DUI Accident

The 20-year-old actress was slightly injured when her convertible struck a curb on Sunset Boulevard. She was briefly hospitalized. Lohan and two other people were in her 2005 Mercedes SL-65 when it crashed around 5:30 a.m., Sgt. Mike Foxen told the Associated Press. "She was cited and released because she has been admitted to a local hospital for minor injuries," Foxen said.

The other passengers in her car were not injured, said police. Lohan's car was towed from the scene at 6:30 a.m. Police are expected to hold a press conference Saturday to give more details on the accident. The actress, who stars in the upcoming movie I Know Who Killed Me, was spotted out at the Hollywood hotspot Les Deux before the crash. She arrived around 11:15 p.m. with a group of friends, and was seen dancing and smoking. Also at the club were singer James Blunt and Paris Hilton, who was recently ordered to 45 days in jail for violating her probation. Hilton was charged with a DUI in September 2006.

Lohan's publicist Leslie Sloane did not immediately return calls for comment. The incident was first reported by X17 Inc., a celebrity photo agency. Lohan checked into rehab in January, saying: "I have made a proactive decision to take care of my personal health." The month before that, her rep told PEOPLE the actress had been attending Alcoholics Anonymous meetings.
