Nicole Richie is famous for doing nothing except being a party girl, but she can add diva to her resume after last night's MTV Australia Video Music Awards.
Sources told "Confidential" that Richie was the only presenter who refused to take part in the dress rehearsal, not leaving her dressing room all day.
Not even boyfriend Joel Madden, from Good Charlotte, could cajole her outside.
Richie is being paid big bucks in appearances fees, so organizers expected her to do the job properly.
Other bigger names such as Pink and host Fergie took part in the rehearsal without complaint.
We also hear that her management had diva demands regarding her dressing room -- unlike the slight star, her room had to be large.
Richie's trip hasn't been a happy one, she upset fans when she arrived at Sydney Airport on Saturday, refusing to sign autographs for many who had waited up to 48 hours for a glimpse of their idol.
Another presenter who we hear has been difficult is Kristin Cavalleri .
Er, Kristin who?
She is a B-grade reality television and soap star in the US, but sources tell us she has refused to do any publicity and is also being a princess.
Her 15 minutes of fame would be limited if that attitude continued, a source said.
Well, at least these 2 divas could get it together for this photo op!
