MTV will be on guard Sunday night against any possible wardrobe malfunctions at its Video Music Awards, but Jessica Simpson says no one will need to worry about her revealing too much during her performance.
Although the pop star admits that this year's show, which is being held in Miami, is "going to be more of a party," don't expect her to kiss Madonna.
"I think leaving more to the imagination is better," she tells the Associated Press. "That's sexier to me."
The annual awards show has generated plenty of controversy since its inception 21 years ago – including Britney Spears and Madonna locking lips at last year's show. But much has changed since last year – especially after Janet Jackson's overexposure during the MTV-produced Super Bowl halftime show – and television execs are less tolerant of what might happen on the air during their watch.
But despite an audio delay to prevent any stray profanities at Sunday's VMAs, it's tough to predict what might happen, MTV president Van Toffler tells AP.
"It simply happens when you put musicians and artists together: They don't always do what you want them to do," Toffler says.
Sunday's VMAs will include appearances by Jennifer Lopez, Gwyneth Paltrow, Hilary Duff and Mary-Kate and Ashley Olsen, who are making their first public appearance since Mary-Kate entered treatment for an eating disorder earlier this summer.
Usher, OutKast, Christina Aguilera, Hoobastank and Simpson are all slated to perform. And top nominees include Jay-Z, who's up for six awards for his gritty black-and-white video "99 Problems," and his girlfriend, Beyonce, who's up for five trophies alongside No Doubt, OutKast and Usher.
