Is Mario Lopez a Prima Donna?

Looks like Mario Lopez is a bossy guy: In helping plan a housewarming bash for his friend, hotelier Gavin Maloof. Mario killed just about every entertainment idea Maloof had, according to New York's Daily News. First, Mario barred his ex-wife Ali Landry from hosting a bikini fashion show (remember, they were married for two weeks until Ali dumped him and asked for an annulment, allegedly because Mario cheated?). Anyway, then Mario turned down Maloof's backup, Cheryl Burke of "Dancing With the Stars" allegedly because the two didn't get along on the show's set. Finally, Maloof had to go with a band. Jeez, it wasn't even Mario's party!
