When we invited Diddy to appear on tomorrow night's episode of FNMTV with Donnie Klang, we had no idea he'd commandeer the commentator's box, attempt to partially choke Jordin Sparks and inspect her dental work while Tim Kash and James Montgomery looked on in horror. At least that's what maybe went down in rehearsals. What's gonna happen on the show? You're gonna have to tune in and see for yourself. Here's what we do know's gonna happen.

Tomorrow night’s FNMTV artist appearances and video premieres:

The Cab - "I'll Run"

Morningwood - "Sugarbaby"

Donnie Klang featuring Diddy - "Take You There"

Plus, an electrifying live performance by Santogold, Best Female Video nominee Jordin Sparks in the hot seat, and Pete Wentz on the mic.

Also, the final VMA nominees for Best Dancing In a Video and Best New Artist will be revealed, and we'll open up nominee voting for Best Rock Video and Video of the Year. It all goes down tomorrow night -- Friday, August 8, at 8pm ET. Until then, check out more behind-the-scenes photos:
