The Safe Haven actor, 44, and the tot faced off to the beat of an instrumental song. Showing off his moves, the Transformers star did a few jumping jacks before hitting the floor for a head spin! Axl tried to follow his dad’s trick, and Duhamel hilariously helped him out by pushing him around in circles on the florescent-colored dance floor.
“I can’t think of a better way to celebrate a 4th birthday,” the former fashion model captioned the clip posted to Instagram. “Happy Birthday Axlito!”
Fergie also took to the social media site to post a series of pictures with the tyke. “Happy 4th bday Axl Jack!!! I love you – mommy,” the “Big Girls Don’t Cry” songstress, 42, wrote alongside a selfie with her son.
“#Doubletrouble,” the former Black Eyed Peas member said of another adorable photo of herself with Axl, who were both sporting plastic crowns. “Happy 4th bday #axljack.”
Two nights before Fergie gave birth, Duhamel appeared on The Tonight Show to dish on his last-minute jitters. “You know, I gotta tell you, I’m a little bit nervous,” he told late-night host Jay Leno. “I thought that I was going to be good. Thought I was ready for this and I’m a little bit terrified. I’m excited and terrified, because I am responsible for this little thing. Forever.”
