My man Billy Joel isn't crying in his coffee over the end of his marriage to wife Katie Lee Joel. Nope, the piano man is already making beautiful music with a new lady -- former soap star Alex Donnelley!

Billy's rep has confirmed to Access Hollywood that he is dating Alex, who once starred on The Young and The Restless. The new lovebirds hit it off when they met backstage at one his concerts earlier this summer.

I know you're wondering if Alex is almost-a-teenager like Katie (okay, she was 27), but she's not. The actress is turning 50 next month. Much more Billy's 60-year-old speed.
