When you have been to rehab as many times as Lindsay Lohan and Brooke Mueller, you start to run into people you know at rehab. Lots of people you have seen before and you both promised that you would never see again except on the outside because you are besties. Then, unless of course you are Elizabeth Taylor and Larry Fortensky, you never see each other again because you don't have anything in common and who wants people to know you are friends with Lindsay Lohan anyway. It should come as no surprise that Brooke Mueller and Lindsay Lohan would end up at the same facility. Who do you think is paying for Lindsay's stay in the facility? Yeah, the same person who is paying for Brooke's and probably has not given up on the idea of having some kind of foursome with his exes and Lindsay when everyone gets out. Free coke for everyone.
