Ozzy promises to sober up for daughter's nuptials

Ozzy Osbourne has vowed to get clean and sober for his daughter Kelly's wedding.

The 64-year-old rocker - who recently admitted he relapsed and has been addicted to prescription drugs for the past 18 months - has promised the 'Fashion Police' co-host that he will get his life back on track before she ties the knot with vegetarian chef Matthew Mosshart so he can walk her down the aisle.
