Lohan, who is navigating her way through life after rehab, moved into a house next door to Ronson's in Venice, Calif., when she left treatment. And Saturday night, the two neighbors broke bread at a nearby restaurant.
After meeting at Ronson's home, the pair headed to Joe's in Venice for dinner. There they "shared a friendly dinner," says a source. "Lindsay has been begging Sam to see her and Sam finally gave in."
After dinner, Lohan, 24 and Ronson, 33, took a stroll around the beach-side neighborhood.
On Monday, the two got talking over Twitter about the basketball battle between east and west that played out Sunday night, with Ronson apparently a Los Angeles Lakers fan and Lohan staying true to her New York roots by cheering for the Knicks.
"I think the knicks are jet lagged. they're getting sleepy right now - someone wake em up!!!" Ronson wrote to her followers the morning after the Lakers beat the Knicks.
Lohan Tweeted back to Ronson: "They played well though :)."
