She's a real night owl!

Mere hours after striking a plea deal in court, which will commit her to 90 days of in-patient rehab, Lindsay Lohan did what she does best and partied at AV nightclub in Hollywood with energy drink mogul Mr. Pink and his entourage, and we can't believe her team didn't put their foot down!

It is still up in the air which rehab facility she will enter, but she better enjoy her days of nightclubbing now because they are coming to an end soon!

Lilo better get used to an early bedtime!
