Lindsay Lohan, Samantha Ronson and Paris Hilton definitely know how to party ... all night!
The 25-year-old Mean Girls starlet started her night at a Hollywood club rockin' Louboutin booties before heading to the private Hollywood Hills party.
The three ladies joined Paris' younger brother Barron Hilton at the Hollywood Hills mega-mansion for some late night fun that lasted until 7am this morning!
Police tell us that one of the neighbors in the residential community filed a noise complaint due to the blaring music.
In our exclusive photos, you can see all the party-goers leaving the mansion after their all-nighter.
Paris and Brandon walked out of the house through the garage. Looks like it was definitely a rough night!
