FergieandJosh Duhameljust took thesnow in Los Angelesto the next level.

The friendly exes reunited over the weekend to join their 5-year-old sonAxl Jackin enjoying the extra-long winter, playing together in a man-made “winter wonderland” alongside other families.

Axl and his singer mom, 43, sledded down the makeshift snowy hill, indulged in a mini snowball fight and grabbed a cup of hot chocolate together in a series of videos Fergieshared to her Instagram Storyon Sunday, set to the appropriate background tune, “Let It Snow.”

In one clip, she cheered from the sidelines as Duhamel, 46, and Axl rode down together. The father-son duo took the trip multiple times, hilariously (and gently) wiping out in one cute video.

Despite their split, theTransformersactor raved about Fergieand how their relationship has evolvednow that they’re no longer a couple, during a December interview withDax Shepardon hisArmchair Expertpodcast.

Duhamel often posts pictures of the former couple’s son on social media and fawns over being a dad in interviews. Shortly before announcing their separation, the actor opened up toEllen DeGeneresabout his life as a father and his parenting style after having Axl at 40.

“I have no idea what I’m doing half the time,” he said. “[Fergie’s] definitely more evolved than I am, and more patient. … Having a kid when I was 40 years old is much different than having one at 22, so I’m a little bit more mature than I was then.”
