Lindsay Parties -- Legally!

Lindsay Lohan took a break from rehab to party on her 21st birthday. Can I see some ID?

Family members, including mommie dearest Dina and lil' sis Ali, showed up to a Malibu beach house this afternoon, bearing gifts for the birthday gal. Other guests were spotted carrying presents in Hermes and Louis Vuitton shopping bags, and a special delivery from Versace was seen arriving to the home as well. The sober starlet sure does love her high fashion!

TMZ caught Lindsay running into the party after exiting a white Mercedes. Lilo left the shindig just an hour later, only to return after 30 minutes -- this time in a Range Rover. Luckily for Malibu residents, at no time was Linds driving.

Feliz cumpleaños
, La Lohan!
