Is it just us — or does Will Arnett seriously get around? After dating Hollywood producer Erin David, the 44-year-old funny guy/cradle robber has a new girlfriend, actress Arielle Vandenberg, who happens to be much younger than the ‘The Millers’ star!

A new report has confirmed their relationship, a month after the actor and Arielle, 28, were spotted together at the 25th annual KROQ Acoustic Christmas in LA last month!

Arielle has appeared on TV shows such as ‘Greek,’ ‘Bones’ and ‘How I Met Your Mother’ and is currently filming a pilot opposite the hunky Josh Duhamel!

A source tells ‘Us Weekly,’ who broke the news of their relationship, “The past few girls haven’t been fun enough for him, he’s a child at heart.”

Since his split from the hilarious Amy Poehler, he’s dated Erin Davis and celebrity chef Katie Lee. Well, here’s to hoping it works out for Will and Arielle!
