Electra has a three-month contract to be Klok's sexy assistant, but "she's throwing fits, crying; there's all kind of turmoil," a source said.

A rep for the show declined to comment on the situation but said the postponement is likely to move the May 12 opening to May 19.

HOT TICKET

The hottest ticket ever? The May 5 megafight between Oscar De La Hoya and Floyd Mayweather Jr. is taking Las Vegas ticket prices into new territory.

"It's the biggest fight in 10 years and will end up being the biggest ever, in demand, interest and ticket pricing, across the board," said Kenny Solky, president of lasvegastickets.com.

One fan is shooting for the moon: He's asking for $35,000 apiece for a pair of so-so seats at the ticket broker Web site stubhub.com.

With the fight two weeks away, choice seats are going for $7,500 to $15,000, Solky said. Seats in the nosebleed section will cost you $1,200.

"The last one that generated this kind of interest," Solky said, "was Tyson-Holyfield on June 28, 1997," the night Mike Tyson bit Evander Holyfield's ear.

This time the fans are feeling the bite.
