Last year, it was reported that the troubled star tossed a beverage at her ex-girlfriend’s head – with Sam later Tweeting about the incident.
The episode happened at popular venue Trousdale and Lindsay claimed at the time she had “learned my lesson”.
But now an insider says the star, who recently left the Betty Ford Center in California, has returned to the bar. She did not consume any alcohol while there.
A source told E! Online that Lindsay visited Trousdale, yet the sighting wasn’t confirmed by the actress’s representative.
Since leaving rehab, Lindsay has vowed to get her life back on track.
Last week, Hollywood veteran Betty White urged the former child star to remember that she has a responsibility to behave due to her famous position.
