After 12 years of marriage Courteney Cox and David Arquette filed for divorce earlier this week. They've both decided to do it without a lawyer, but get this! The couple does not have a prenup, which means that everything they earned during the 12 years they were together is going to be divided 50/50! Uh-oh, Courteney! During the last years of "Friends" Courteney pulled in a fortune, and now David could be entitled to half of it. Reportedly she's worth about $75 mil and he's "only" worth $18 mil. Watch out, Courteney, this can be big troubles coming up! (tmz)
