The 25-year-old starlet, who will be attending the White House Correspondents' Dinner tomorrow night, was scheduled to leave today at noon.

Lilo was partying until 6am this morning at a home in the Hollywood Hills. This was the second night in a row that she pulled an all-nighter at that house.

No wonder she missed the flight!

The Mean Girls star will now be forced to take a red eye.

Let's hope Lilo gets it together before meeting face-to-face with President Obama!
