Kelly Osbourne says marriage will make her a "cracked-out housewife." The 24-year-old star - who recently completed a stint in an Oregon rehab clinic where she was treated for an addiction to painkillers - is planning a long engagement to her fiance Luke Worrall, 19, as she thinks the pressure of married life could prove too much.

She told People magazine: "I think the last thing I should be doing right now is planning a wedding. I'd become one of those cracked-out housewives with a vacuum cleaner, hopped up on Dexedrine."

Friends of the 24-year-old star have blamed Kelly's wild lifestyle in the U.K. city for her latest stint in rehab.

A source said: "It's a very party atmosphere there. Kelly just tends to get back into that rut when she's there since her friends are there, and she's just more comfortable there. The old party habits come back."

Kelly Osbourne is in rehab. The 24-year-old star has checked in to a treatment facility just outside Los Angeles, but no further details have been released.

Her mother Sharon confirmed: "Yeah, Kelly's in rehab. What else can we say? She knew that it was the right thing to do at this point and we're proud that she did it. The family is all standing behind her. Kelly knew that she needed help and she's getting it."
