Lindsay Lohan and Samantha Ronson went to Matsuhisa in Beverly Hills last night after LL's sexy photo shoot. On Sunday, Samantha called in to Loveline to talk about DJ AM and Travis Barker's plane crash, and when LL jumped on the phone, Stryker asked how long she and Samantha had been dating. You can listen to the audio after the jump, but Lindsay answered: "A long, very long time" and thanked him when he said she and Sam make "a lovely couple."
