Super reality couple Heidi and Spencer Pratt made a surprise visit to "Extra's" studios to debut Heidi's new music video, "Blackout," and then Spencer dropped this musical bombshell on Mario Lopez: He's pulling a Joaquin Phoenix and heading into the world of hip hop!

"I've always been a huge hip hop fan. I've been listening to the radio a lot recently and been a little disappointed in what's out there in hip hop," he explained.

Spencer's new single, "I'm a Celebrity," debuted this morning on Los Angeles' KISS FM and he's confident in its success. "I honestly think I'm a better rapper than anyone else in the game. I don't try to rap and I'm better than you guys."

Heidi and Spencer, soon headed to the jungles of Costa Rica to star in NBC's "I'm a Celebrity, Get Me Outta Here," revealed Heidi's dream duet is with future castmate and "American Idol" castoff Sanjaya. "He can sing for us," she said. "Him and I can do a duet around the fire."

Heidi's video for her new single, "Blackout", can be seen exclusively here! The single will be available on iTunes Tuesday, May 19th. The album hits stores July 7th, but it doesn't yet have a title.
