Look Back at Fergie & Josh Duhamel's Cutest Family Photos

Fergie posted this sweet shot for her son's birthday in August 2017. "Happy 4th bday axl jack!!!" she wrote on Instagram. "I love you -mommy."

Josh excitedly brought Axl to the North Dakota State Fair in July 2017. (The 44-year-old actor grew up in Minot.)

Josh and Axl got their friends and family together to wish Fergie a happy 42nd birthday in song. "HAPPY BIRTHDAY FERGIE FERG!!! Love you madly, JD, Axl and Company," the Transformers star wrote on March 27.

There was no sign of trouble when Josh posted this family photo to Instagram to celebrate his and Fergie's 8th wedding anniversary in January 2017. "8 years!! Love you babe," he wrote.

Axl couldn't get enough of his dad hamming it up when the whole family met Santa in December 2016.

Fergie shared a #tbt in September 2016 of her jet-setting family's trip to England.

The proud parents brought son Axl to his first Los Angeles Dodgers game in August 2016, where Josh had the honor of throwing out the first pitch. The Dodgers are Fergie's home team -- she grew up in Hacienda Heights, a suburb of L.A.

"Thank u daddy @joshduhamel 4 the snow in cali! (somebody was super happy to have hot cocoa…)," Fergie wrote on Dec. 16.

Fingers crossed that Josh and Axl star in a Top Gun remake! "My son thinks I can actually fly an F16. Let's just go with that for a while..." Josh said of this adorable photo shared from the duo's visit to California's March Air Force Base in April 2016.

The Duhamel family's 2015 Christmas card was pure perfection.

The couple was adorably goofy at the 2014 American Music Awards.

Josh and Axl visited a bikini-clad Fergie while she was filming the music video for her song, "L.A. Love," in November 2014.

"He's picking out my birthday gift," Josh quipped of his son's nosing around in November 2014.

Axl dressed up like a skunk for Halloween 2014. "First trick or treat!!! Daddy's lil stinker :)," Fergie captioned this precious Instagram post.

Axl may be the cutest Wu Tang Clan fan ever! "Had to post this... Axl giving some east coast love. #wutangforever," Fergie wrote in September 2014.
