MTV Did Kelly get fake boobs?

272kg quad

300kg quad

There are a lot of articles out there. they don't seem too negative about atv's. Most of them just say that he wrecked one. If the links don't work, the first one is an injuryboard. It popped up with those two little words. Ozzy and atv. The last two didn't seem to work but they both stated different weights for the quad.
