She turned 23 years old yesterday (July 2) and it looks like Lindsay Lohan took full advantage of her birthday status with a day full of fun.

The “Mean Girls” hottie was spotted out with her on/off girlfriend Samantha Ronson, enjoying a swanky meal at Cecconi’s restaurant in Malibu, California.

LiLo looked a bit annoyed with the paparazzi as she arrived at the restaurant sporting a sexy white minidress underneath a black leather jacket.

Earlier in the day, Lindsay and Sam were spotted chatting it up over lunch, and from the looks of it they weren’t able to finish their pizza as Lohan was carrying a to-go box.
