Comedian Will Arnett has reportedly embarked on a new romance after quietly splitting from celebrity chef Katie Lee earlier this year (13). The Despicable Me star confirmed his romance with Billy Joel's former wife in August (13) but reportedly called it quits with her soon afterwards. However, it seems Arnett will not be spending the festive season alone after sparking speculation of a new romance with Hollywood producer Erin David, who he accompanied to Jennifer Aniston's holiday bash earlier this month (Dec13). A source tells Usmagazine.com, "Will and Katie Lee fizzled. He lives in L.A., she lives in NYC. "(David) produced one of the shows or a film he was in... Will brought her to Jen and Justin (Theroux)'s holiday party." The comedian was previously married to actress Amy Poehler, but the couple split last year (Sep12).
