If you thought the music apocalypse was upon us when Kris Allen shockingly won American Idol last night, that was just a precursor to the real thing:

Spencer Pratt's new rap single is now available on iTunes.

"I feel honored to now be a part of music history and be able to say I have the second best music on iTunes for sale next to my wife Heidi!" he said.

We think he meant to say second worst.

The Hills star, who raps under the name "The Great White," recently debuted his rap skills, or lack thereof, on a song called "I'm a Celebrity."

The song - recorded for I'm a Celebrity, Get Me Out of Here, which will star Spencer and wife Heidi Montag among others, hit the web last week.

Spencer Pratt said, "First I took over TV, magazines and the internet - now I'm going after the airwaves... Nothing can stop 'The Great White.'"

Lyrical gems from the track include a Twitter shout-out: "First Tweet of the day, I put my swag on... I'm in the limelight and I love it like my wife."

That really sums it up. Spencer and Heidi Pratt tied the knot April 25, and their wedding will be shown on the season finale of The Hills May 31.

I'm a Celebrity, Get Me Out of Here debuts later this summer.
