Ozzy Osbourne is hitting the road again. The aging rocker — who

announced earlier this week that he was taking a three-week break from Ozzfest while his wife Sharon underwent treatment for colon cancer — has cut his leave of absence short. "After attending Sharon's first chemotherapy treatment, he nearly passed out and had to be taken to a recovery room," the couple's rep said. "Sharon now realizes that Ozzy is better off on the road, so she's shipped him back out to finish Ozzfest." (Let's hope MTV captured that on tape.) Osbourne will rejoin the tour in Clarkston, Mich., on Aug. 7.
