A source tells PageSix:

    "There was no way she was going to stay home with her mom. She had dinner, and then, bringing along her water bottle, went clubbing to SL, where she hung out with Tyson Beckford and got in the booth with DJ Phresh. She seemed totally sober and upbeat. She asked if Sam Ronson had been there the night before."

As for what her family thinks of the late-night partying, the source adds:

    "Her family is furious. She's supposed to be spending time with them and deciding if she'll take a plea deal. It's almost as if she thinks she may as well have one last final fling."

Lilo will have to decide by March 25 whether or not she'll plead guilty to allegedly stealing a $2,500 necklace from a Venice Beach jewelry store. If she seeks a plea deal, the judge said she will most certainly face jail time.

Aside from all the partying, Linds seems to be making a little time for her family. Find out where she went last night with sister Ali and brothers Michael and Cody ... after the jump.
