Will Arnett Girlfriend 28 - The 44-year-old actor and his new girlfriend Arielle Vandenberg 'stole the show' on the red carpet at the after party for the 72^nd Golden Globes Awards on Sunday.

Will Arnett's girlfriend, 28, could not keep herself from smiling heartily as they posed for photos at the Nexflix and Weinstein Company after party. This is the second time that the couple have been spotted in public together. During Christmas, they attended a party in LA together, according to US Weekly.

Some critics have noted that it must be somewhat awkward for Arnett's ex-wife Amy Poehler that he was flaunting his new relationship at the award show she hosted. But reports indicate that despite the fact that Arnett went on to file for a divorce in April 2014, him and Poehler have remained friends since their separation in 2012 and continue to raise their two sons together.

Poehler revealed in her book Yes Please, which was released last year, that she had difficulties dating again after her divorce. In the tell-it-all book, the 43-year-old comedienne said she went on a date with actor John Stamos. However, reports indicate that since last year the Parks and Recreation actress has been dating Nick Kroll.

Meanwhile, Arnett has also had flings of his own. He was reportedly in a relationship with producer Erin David, which was supposedly ended before he started going out with his current girlfriend.

It is unclear how long Will Arnett and Arielle Vandenberg have been in a relationship, but insiders say Arnett is enjoying their time together. "The past few girls haven't been fun enough for him, he's a child at heart," the source told US Weekly.

Catch Will Arnett's girlfriend Arielle Vandenberg in CBS new drama TV series Battle Creek, which premieres in March.
