The newly single beauty dressed casually for the outing in a straw hat, black leggings, a blue tank top, and sneakers.
As fans of Joanna know, she is a huge animal rights activist, and even founded a charity called Angels for Animal Rescue with a friend to support and encourage the humane treatment of rescued kittens, chickens, pigs, boa snakes, and more.
While at the park, Joanna, 38, killed some time on the swings while her dogs played.
Just last week, Joanna’s divorce was finalized, after she and Romain Zago called it quits. It’s been a pretty amicable split, with no crazy stories in the media about their relationship, which is certainly a rarity in Hollywood these days.
Joanna said about their breakup that she is “grateful” for the times they shared and they "wish each other nothing but continued happiness and success."
