Lindsay Lohan got another visitor Thursday: Former girlfriend Sam Ronson.

A day after the 24-year-old was greeted by her mother Dina and teen sister Ali, Ronson popped by the Century Regional Detention Facility in Lynwood, Calif., where Lohan is confined for at least the next two weeks for violating probation from her DUI case.

Though they had a nasty split, Ronson has been by Lohan's side ever since she was sentenced to the slammer July 6.

Last week, she visited the actress at the sober-living facility where Lohan had been residing and even defended her on Twitter when crass comic Joan Rivers made some mean jokes.

"Pick on someone your own age," Ronson wrote Rivers. "Oh wait I guess people that old can't hear."
