John Cena will be a special guest on Late Night with Conan O'Brien tonight. It's The Champ's second time on the NBC talk show, and he said he's looking forward to hanging with O'Brien again.

"Conan's great," Cena told WWE.com. "He's a Boston guy, and he's got a great sense of humor -- so witty."

Tonight, Cena plans to talk about being spokesperson for the Make-A-Wish Destination Joy campaign, competing in the ABC reality series Fast Cars and Superstars -- The Gillette Young Guns Celebrity Race and the upcoming Vengeance: Night of Champions pay-per-view on June 24.

"It'll be really fun and I know he'll have some surprises for me. I have a few things for him, so it's always fun to do this show," Cena said.

Late Night with Conan O'Brien airs at 12:35 a.m. ET on NBC.
