It's been less than a year since Will Arnett and Amy Poehler split, but it sounds like the Arrested Development star has already found himself a new leading lady. Back in May he denied any dating activity, but according to E! News the actor has been spending some quality time with celebrity chef Katie Lee. This is the first woman that Will has been linked to since parting ways with his ex-wife back in September. And in case you didn't know, Katie Lee's famous ex is none other than Billy Joel.
