Stars such as Lindsay Lohan, Snoop Dogg and Ashton Kuchter are heading to Florida for the US Super Bowl.
Carmen Electra and Jenny McCarthy will also be in town to host a party which they promise will be "sexy and fun".
The annual Leather And Laces party is also hosted by US reality TV star Kim Kardashian.
Carmen, who hosted a party with Jenny at the Super Bowl last year in Phoenix, said it was a party for everyone - even those who don't like sport.
"I think sports fans are very enthusiastic, so during the Super Bowl there's a lot of energy, a lot of people. It makes for a much more fun, lively party.
"It's going to be sexy and fun, and it's always going to be crazy at the Super Bowl," she said.
Kevin Costner is also hosting party, at which his band will play, to raise money for charity.
"It's clearly not the need for attention. I've had enough of that for a lifetime," he said.
His gig is going head-to-head with gigs by hip-hop artist T-Pain and rap mogul Sean "Diddy" Combs, along with an affair crawling with Playboy hotties called Models And Bottles, and an event at a science museum hosted by Nelly.
Another party at the Hard Rock Hotel & Casino is hosted by Kevin Dillon of Entourage fame, and Jessica Simpson's ex-husband Nick Lachey is also hosting an event.
