Osbourne works for Epic Records

Jack Osbourne, the son of rocker Ozzy Osbourne, has said he checked himself into a drug and alcohol clinic in California last week because he wanted to sort out his problems.

"I got caught up in my new lifestyle and got carried away with drugs and alcohol," he told People magazine.

The Osbourne family became international stars last year after being featured in a fly-on-the-wall series on MTV.

His father has had well-documented problems with substance abuse and recently turned to alcohol again when his wife was diagnosed with cancer.

"I voluntarily checked myself into a detox facility for my own health and well-being," said the 17-year-old.

His father said he was proud of his son for admitting he had a problem.

"It takes a lot of courage and strength to admit you need help, and both Sharon and I are proud Jack is facing his problems head-on," he said.

Sharon Osbourne has reportedly said she blames herself for son Jack going into rehab after allowing him to appear in the family's reality TV show.

She has told the ABC network that the second 10-episode series of The Osbournes would be the last.

Osbourne said the show - which drew record ratings for MTV this spring - had changed her family "so much".

Her children, she said, now had lawyers and business managers.

"This is definitely the last year," Osbourne said. "We can't do it anymore."

The first series was a big hit around the world but ratings tumbled in its second season.
