He won't be fighting in the ring, but instead helping out the creative team behind the scenes. Freddie Prinze Jr, one of the stars of "I Know What You Did Last Summer" amongst other films, will assist with the WWE's Monday Night Raw show, as well as Pay Per Views and the other weekly WWE shows.

From Marketwatch.com:

"Bringing on board an experienced Hollywood writer, actor and producer like Freddie Prinze, Jr. will only increase the level of entertainment to millions of viewers and passionate WWE fans every Monday on USA," said Chris McCumber, Executive Vice President Marketing Digital & Brand Strategy, USA Network."
"Freddie Prinze, Jr.'s passion, energy and creativity make him an excellent fit for WWE," said WWE Chairman Vince McMahon.

Another celebrity, who may be more or less known than Prinze Jr. is Piers Morgan. Morgan found fame most recently on Donald Trump's "Celebrity Apprentice". The businessman/mogul will be appearing on this weekend's "Saturday Night's Main Event" along with Ben Stiller, Billy Ray Cyrus, Toby Keith and Jenny McCarthy. All of the celebs will be on hand as part of "Generation Rescue", the project McCarthy is heading up to fight Autism.

According to Digital Spy:

Speaking about the event, Morgan told The Sun: "I'm delighted to help with such a worthy cause.

"My kids are huge WWE fans, so there was no way I could turn down the opportunity to fight this cause alongside WWE's superstars."

Jenny McCarthy added: "I love the WWE and when Vince McMahon called me and said he wanted to join the fight and help families suffering with autism, I was really excited.

"Who better to have on your side in a fight than WWE?"
