'Lonely' Lindsay Lohan Drunk Dialing Her Ex, Samantha Ronson

RadarOnline.com has learned that a "lonely" Lindsay Lohan has been drunk-dialing her ex-girlfriend Sam Ronson — and insiders say she would do anything to win her back!

"Lilo doesn't care that Sam's in a long-term relationship," an insider told RadarOnline.com. "She can't get out of her head that she and Sam were soul mates, so it doesn't compute in Lilo's brain that Sam might actually have found love somewhere else."

As RadarOnline.com reported, Lohan and Ronson, who is dating makeup artist Lauren Anderson, had a famously turbulent relationship, filled with bitter fights, breakups and makeups.

Despite 38-year-old Ronson's current relationship status, Lohan, noted the insider, is always saying that her former flame is "the one who got away."

Ronson has been patient with Lohan, 29, so far, refusing to block her number, despite her new girlfriend's wishes. Unfortunately for the DJ, Lohan has misread her good intentions as a sign they could still rekindle their romance.

"It's only when Lilo's had too much to drink that she calls her, but to be fair to Sam, she is starting to get tired of it as the calls are becoming more and more regular," said the insider.
