Will Arnett, star of The Millers and Arrested Development, appears to have a new girlfriend.

According to Us Weekly, Amy Poehler's ex-husband is now dating Erin David, who executive produced his old NBC series Up All Night. She also co-produced Amy's movie Baby Mama and worked as an associated producer on Saturday Night Live, so Amy probably knows Erin as well as Will does.

Anyway, this means Will's relationship with Katie Lee must've been arrested in development. (Lame. Sorry.) Will and Billy Joel’s ex-wife were rumored as a couple starting back in August. However, an insider told Us Weekly, "Will and Katie Lee fizzled. He lives in LA, she lives in NYC." The old distance issue again. It's a killer!

Will also took Erin to Jennifer Aniston and Justin Theroux's December 8 holiday party, and Us has a not-terribly flattering paparazzi photo of the new couple either leaving or arriving at the party in his car.

It does seem like someone with Erin’s SNL/comedy producing background might have more in common with Will than celebrity chef Katie. But that’s just a guess. Amy has been linked to comedian Nick Kroll since early May, so she also connected with someone in a similar industry.

Amy, 42, and Will, 43, split in September 2012, and they have two young sons together.
