Alberto E. Rodriguez/Getty Images for Geffen RecordsYou didn't know permabesties Samantha Ronson and Lindsay Lohan were also friends with Solange Knowles? We didn't either.
Turns out, maybe they're not, despite this photo of the threesome from Solange's 22nd birthday bash.
According to People, Sam was actually working at the party. She was hired to deejay the bash, held at a private mansion in the Hollywood Hills. And as for Linds...
She came early while Sam set up the turntables, but left before most guests arrived around 11 p.m, including Beyoncé, Ludacris, Mario and Ne-Yo.
Big-sister B made sure guests didn't go hungry. The menu included barbecue chicken, cornbread, greens, mac and cheese and of course, cupcakes. As for the music, Sam spun all of Jay-Z's and Beyoncé's hit songs, at Solange's request.
No word on whether any of the birthday's girl's own jams were actually played.
