Getting ready for the big game: Fergie treats her football-mad son Axl to a healthy snack ahead of the Super Bowl 

It was the biggest day of the year for American football fans.

So no wonder little Axl Duhamel looked excited as he headed out with his mother Fergie to grab some snacks ahead on Super Bowl Sunday.

The Black Eyed Peas singer, 40, took her young son Axl, two, to pick up some healthy treats from Acai Nation in the LA suburb on Brentwood on Sunday.

Although his parents' respective teams didn't make it to the American football final, Axl showed his support for the Miami Dolphins in a team jersey.

The toddler's mother Fergie is a part-owner of the Florida team, having become a celebrity minority investor in 2009.

However, his father Josh Duhamel is a huge Minnesota Vikings fan and makes sure Axl wears his team shirt when they're out together.

Stick to slogan sweatshirts for your off-duty style

Fergie was the queen of casual-cool as she headed out with her son Axl before the Super Bowl. She worked off-duty style in the form of skinny jeans, trainers and a sweatshirt and we were instantly looking up where to buy her look because we were digging it!

The sweatshirt that refers to Karl Lagerfeld - the creative Director of Chanel - is one that's proved rather popular with a whole variety of celebrities from Kylie Jenner to Lauren Pope.

The quirky sweatshirt is by Eleven Paris and if you're keen to snap one up for yourself, click right to buy it now at Bloomingdales.

Fergie teamed her look with a Fendi bag and slip-on trainers which are also available (below) so bag the lot and team with your favorite skinnies and you'll be working Fergie's casual look in no time at all.

She completed her look with a leather-look scarf, sunglasses and carried an oversized Fendi tote bag.

Missing out on the outing was Fergie's husband Josh, with whom she celebrated their seventh wedding anniversary last month. 

Speaking last month, Transformer hunk Josh, 43, said the couple went up the California coast to Big Sur for a romantic anniversary break.

He told Entertainment Tonight: 'We just went up to Big Sur for a couple days. It’s one of the most beautiful places in the world.

'You know, we still really really like each other. That’s important.'
