He's got a new gal! After quietly splitting from girlfriend Erin David, Will Arnett is now dating actress Arielle Vandenberg, Us Weekly can confirm. The couple were recently spotted out together at the 25th annual KROQ Acoustic Christmas in L.A. last month.

"She loves to laugh," a source tells Us. "The past few girls haven't been fun enough for him, he's a child at heart."

Vandenberg, 28, has made guest appearances on TV shows such as Greek, Friends with Benefits, Go On, and For Better or Worse. She's currently filming the pilot for the new series Battle Creek with Josh Duhamel.

Us broke news in December 2013 that Arnett, 44, and producer David were dating. "Will and Erin were on and off for a while," a second source adds.

Arnett was previously linked to celebrity chef Katie Lee and separated from Amy Poehler in September 2012 after nine years of marriage. The exes are parents to sons Archibald, 6, and Abel, 4. The Parks and Recreation actress has been dating comedian Nick Kroll since May 2013.
