Lindsay Lohan's Desperate Wait for Ronson

Lindsay Lohan's on/off romance with Samantha Ronson is on life support again following a breakdown outside the DJ's Hollywood home on Sunday.

Footage of the desperate actress sobbing "Where were you?" as her girlfriend returned home after a night out with her sister was caught by Hollywood.tv cameras.

Sources claim Lohan spent the night partying at Playhouse nightclub before heading back to Ronson's house, where she spent two hours waiting for the DJ.

The couple reconciled in London in June after splitting up earlier this summer.
