Will Arnett is dating Billy Joel's ex-wife.
The 'Arrested Development' star, who split from actress Amy Poehler last September after nine years of marriage and shares custody of their sons, Archie, four, and Abel, two, is reportedly romancing celebrity chef Katie Lee, 31, who was married to the 'Uptown Girl' hitmaker for five years until 2009.
A source told E! News that the brunette beauty is the first woman that Will, 43, has seriously dated since his split from Amy last year.
The actor, who was also married to 'The Artist' actress Penelope Ann Miller for a year until 1995, insisted in June that he still believed in love but was scared of dating.
He said: ''Certainly. I do. I do. I'm not officially dating. I don't know what you do. Do you put out an announcement in the trades? I'M DATING! It all seems very scary to me, to be honest. So I'm kind of keeping pretty close counsel right now.''
Amy, 41, began dating fellow comedian Nick Kroll six months after she announced that she was getting a divorce and they went public with their relationship in May.
