Will Arnett is reportedly dating interior designer Elizabeth Law.
The 40-year-old actor has been romancing the 30-year-old beauty - whose work can be seen on her website, Elizabeth Law Design - for a few weeks and they are currently having a lot of "fun".
They were most recently spotted together at celebrity hotspot The Nice Guy in West Hollywood on Thursday, August 25.
A source told the new issue of Us Weekly magazine: "They're having a lot of fun. Elizabeth, who is also known as Law Slagsvol, is related to Jimmy Buffett and used to date Don Johnson's son Jesse."
Arnett split from his wife Amy Poehler in 2012 after nine years of marriage and their divorce was finalised in August with neither person getting spousal support and they share joint custody of their sons, Archibald, seven, and Abel, six.
Since that break-up, the 'Lego Movie' star has been romantically linked to celebrity chef Katie Lee and actress Arielle Vandenberg.
Poehler was in a relationship with comedian Nick Kroll but that ended after two years in September 2015.
Arnett admitted he dealt with his marriage breaking down by "going to the gym obsessively for nine months" and focusing on making sure his kids were OK.
His 'Teenage Mutant Ninja Turtles' Megan Fox has previously revealed she teased him over his choice of young girlfriends when they filmed the 2014 movie together.
She shared: "He was sort of dating a lot and every other week there was a new girlfriend and he would bring them to set.
"They were progressively getting younger and younger as the weeks went on, and it got to the point where I was like, 'Buddy, I'm worried. Should I talk to craft service and make sure they have Lunchables for your girlfriend?' There's no food here with cartoon characters on it.' "
