Sharon to Ozzy, I Just Can't Quit You!!!

Ozzy and Sharon Osbourne are clearly life partners through thick and thin ... as they demonstrated Saturday in Malibu.

They were smooching with their pooches during a walk in the sun.

As you know ... their 34-year marriage was on the rocks a few months back after Ozzy's affair with his hairdresser surfaced.

They make it work.
