After getting caught sneaking her sis into Crown Bar Friday night, Lilo laid low with her sis on Sunday, taking her out to dinner at Taverna Tony's in Malibu.

Granted, it's a Holiday weekend, but shouldn't Ali be spending the weekend back-to-school shopping in Long Island with mom rather than sharing coffee and ciggys with her big sis?

And we love Lilo, but is she really the best example for Ali to be following? Dina, come pick up your daughter, stat!
