Gwen's son looked adorable in his green and white onesie with little monsters on his feet

Blake kept it casual in his black button-up shirt with jeans and a blue hat.

He pushed the cart in front of him that carried plenty of groceries, including some diet Dr. Pepper

The couple got some cart pushing help from one of the employees at the grocery store who brought out another cart that carried even more purchases.

Gwen made her way through the lot where she looked natural with a small hint of makeup.

She had her platinum blonde hair tied back and carried a colorful purse along the way. 

When the pair got to the car, Gwen picked up her son to strap him in his car seat. 

Blake put some of the bags in the trunk as he was seen carrying a tote bag.

On their way home, it appears that the two are about to set off for one amazing Sunday as the Patriots take on the Falcons. 

Gwen is also a mom to two other sons: Kingston, 10, and Zuma, eight. She was previously married to Gavin Rossdale.

Blake was married to singer Miranda Lambert before they got divorced in 2015.

The two stars began their relationship when things began to blossom while working together on music competition The Voice as judges. 

Blake won a People's Choice Award this year for Favorite Album and Favorite Male Country Artist where he referenced his girlfriend while giving his speech.

'Got a lot of people to thank. Thank the hottest date here tonight, Gwen Stefani, who's sitting right there!' the country star said.
