Aside from all trials and tribulations, Aaron (Jonah Hill) gets Snow (Russell Brand) to the Greek theatre in LA.
While Snow puts on a performance sure to restart his career, Aaron tells Sergio (Diddy) that he is quitting. He then returns home to his girlfriend, makes up with her, and the two promise to make more time for each other in their relationship.
We then flash forward to Snow putting on a show in a small theatre, praising his reunited union with wife Jackie Q (Rose Byrne) and his new producer... Aaron!
