The two were spotted leaving Sweet Butter Café in Studio City, California on Wednesday. Green held the door open for Fox as she trailed a few steps behind him.
Green, 42, kept to his typical relaxed style for the afternoon outing, wearing a gray t-shirt with cropped sweatpants and tennis shoes. The actor, who was involved in a 2014 car accident with Fox, still appeared to be wearing what looked like a motion sickness bracelet on his wrist.
Fox, 29, matched her exes casual look, donning a pair of black cropped leggings, a black t-shirt with the word "Rogue" written across the chest with a pink and blue flannel shirt tied around her waist and a pair of neon pink tennis shoes.

The exes seem to have remained amicable since their split, having been spotted together several times. While they've reunited to spend time with their two children, Noah 3, and Bohdi, 2, they've also been seen running errands together without the kids.
In August, the two confirmed their split after five years of marriage and 11 years together, with Fox filing for divorce just days later.
Fox cited irreconcilable differences as the reason for their split, with the date of separation listed as June 15.
