and Samantha Ronson turned date-night into a family affair Sunday, when they dined at New York's Bar Pitti with their moms, Dina Lohan and Ann Dexter Jones.
"All was calm," said an onlooker. "They weren't too animated."
Later, after noshing on the restaurant's Italian fare, Lindsay and Ronson slipped outside for a quick smoke-break.
All in all, the group seemed subdued but happy – and quite comfortable with each other.
"Dina tousled her hair a lot, like you see her do on TV," said the fellow diner. "They all looked very natural, like they've hung out before."
The elder Lohan has been vocal in her support of Ronson, who some see as a stabilizing influence in Lindsay's life. As Dina told PEOPLE earlier this year
, "Samantha is an angel."
Lindsay appears similarly close with the Ronson clan. The actress was recently spotted hanging with the deejay's extended family
during a Miami getaway.
