Diddy, 'WrestleMania 29': Sean 'P. Diddy' Combs Performing at WrestleMania in MetLife Stadium, Co-Hosted 'Superstars for Sandy Relief' Party, Ambassador for WWE's 'Be a STAR' Campaign

Sean Combs aka P. Diddy, aka Diddy is set to perform live at WWE's "WrestleMania 29" this Sunday April 7. The event is wrestling's equivalent to the Super Bowl and will be taking place at East Rutherford, NJ's MetLife stadium, just miles from New York City. WWE CEO Vince McMahon and a number of wrestlers have been heavily promoting the event this week. This will be Sean "Diddy" Combs second appearance at WrestleMania. Diddy also co-hosted the "Superstars for Sandy Relief" party with Vince this week.

Combs has worked with WWE in the past. At "WrestleMania XXVIII" he introduced Machine Gun Kelly when he performed his song "Invincible." Diddy also performed "I'll Be Missing You" at WWE's "Tribute to the Troops" show in 2010. This year, Diddy is not only co-hosting WWE's "Superstars for Sandy Relief" party, but he also will serve as an ambassador for WWE's "Be a STAR" anti-bullying campaign.

Although wrestling may not be for everyone, WWE's WrestleMania pay-per-view is a huge event with lots of eyes watching. "WrestleMania is one of the biggest spectacles in the world and I'm looking forward to performing in front of millions on April 7," Combs told WWE.com. "I've always been a fan of WWE and I'm excited to support these two important causes, Superstars for Sandy Relief and the Be a STAR anti-bullying initiative."

Vince McMahon tweeted a picture of himself, Triple H, Stephanie McMahon, The Rock, and Diddy while doing promotion for WrestleMania. You can check out the photo here.

Vince McMahon also teased a big announcement for Friday April 5 with his very first Tweet on Monday. "Hello @WWEUniverse! The Chairman is now on @Twitter. Get ready for #BigReveal on Friday night. In the meantime...#RAW," Vince McMahon tweeted. One rumor is that Vince will be announcing who will be singing "America the Beautiful" at "WrestleMania 29" this Sunday.
