John Mayer Plays Matchmaker With Sam And Lindsay!

I hope he knows who he's getting involved with!

Yesterday Lindsay Lohan tweeted at John Mayer, "@johncmayer shhhhhhhhhhhhhh butter-face :)" and it looks like we've discovered the story behind her cryptic tweet. According to Gatecrasher, John played relationship counselor at Butter in NYC the other night, and it looks like he may have actually helped patch things up between the ladies!

A source tells Gatecrasher, "Lindsay and Sam didn't arrive together. Lindsay walked in, and the two said a quick hello, but then Linds went to the table where John was sitting." While Sam eventually came over to the table, she sat far away on the opposite side. "Lindsay looked upset that Sam hadn't come over to her, and she started whispering to John, who looked like he was trying to calm her down," says the eyewitness. "She looked pretty angry. Then John got up and went to talk to Sam."

So what happened next? Sam and John went over to Lindsay and the girls spent most of the night chatting and laughing, just like old times! We'd love to know what John had to say...it sounds like he really knows women! Er, has a lot of experience with them?

"Lindsay seemed happier than she has in ages," the spy added. "Sam eventually got up and deejayed for a while, and Lindsay kept standing up and looking over to the deejay booth, smiling ... Lindsay and Sam both stayed past 3. They didn't leave together, but they definitely ended the night on good terms."

Awww, we just hope Lindsay doesn't confuse this friendly gesture with a romantic invitation...after all, Sam's totally over Lindsay, right?
