This is from Amazing Spider-Man #605, by Fred Van Lente and Javier Pulido. The cover is by Mike Mayhew.
The story takes place six weeks ago (ie, before MJ returned in #600). We see a flashback to MJ having an argument with Peter.
Meanwhile, MJ's celebrity boyfriend Bobby Carr is taking MGH so he can get the role of Captain America in a new movie. The DEA is after him because they want his dealer, who turns out to be the White Rabbit.
MJ knocks out one of the White Rabbit's minions and takes her outfit.
MJ manages to subdue the Rabbit with a cream machine from the set, and the police arrive. Afterwards she gets into an argument with Bobby about his MGH usage and dumps him, and takes up an offer she received earlier to host the "Sewn Up" reality show in New York.
