Lindsay & Sam's Family Dinner

If bringing your significant other to hang out with your family is a sure sign of a steady relationship, then consider Lindsay Lohan and Samantha Ronson rock solid.

The actress and her DJ galpal dined with Lindsay's mother, Dina Lohan, and Sam's mom, British socialite Ann Dexter-Jones at Bar Pitti restaurant in NYC's West Village Sunday night. The foursome nibbled olives, dipped bread in fresh olive oil and sipped water while chatting.

“Everyone was laughing,” an eyewitness tells OK!. “They seemed to get along really well. Samantha and Dina were sitting next to each other to gossip.”

The true sign of love? While Sam was talking, our eyewitness says "Lindsay hardly looked at her phone once!"
