Ozzy Osbourne has hinted that the 2007 Ozzfest tour may be his last - because he fears he hasn't got the energy to hit the road again. The rocker headlines the summer trek again with Hatebreed and Lamb of God, which this year is free to fans. And he's telling fans to make the most of the show - as it could be his last.

He tells Guitar World magazine, "At my age, I don't know how many more of these tours I have left in me. This could be the last one. It's a hell of a lot of responsibility for me. If I get sick or if my voice gets blown out or whatever the f%#$ happens, and I can't make a show, the audience gets pretty f%$king mad."

Osbourne founded the annual summer rock festival in 1996 and announced last year would be his last.
