Aha! Not only did they spend some time together at the Andy Lecompte salon on Sunday, but Britney joined Lindsay at the Grand Star Jazz Club in LA later that night!

Britney showed up to the club shortly after 2am, where she hung out with our fav rehabber and danced and chatted. An insider tells Life & Style, “There was no craziness, just a lot of fun and dancing." The former party pals stayed until the club closed, around 3am, and while it looks like nothing too crazy happened (no car chases or random British accents) we gotta wonder what these two are doing hanging out together!

Think they'll hang out again soon? And do you think Britney could be a good influence on Lindsay?
