Lindsay Lohan is a Birthday Babe

Lindsay Lohan goes out for lunch to celebrate her 23rd birthday with Samantha Ronson on Thursday (July 2) in Malibu, Calif.

The Mean Girls actress later headed to Cecconi's restaurant to celebrate for the rest of the night.

Recently, LiLo shared a little about her work ethic. 'I work harder than most of my friends' parents,' Lindsay said. 'I'm the hardest-working person I know. I'm a workaholic. I don't know what to do when I'm not working. I get creatively frustrated.'
