Sarah Michelle Gellar and Freddie Prinze Jr. are one of Hollywood’s longest-lasting couples, but they largely keep their marriage out of the public eye. Luckily, Prinze Jr. has come out with a new cookbook, Back to the Kitchen, which provides a look at his private life with his wife of 13 years and their two children. The book is filled with sweet shots of the family together in the kitchen (see below for one cute example) and we’ve even gotten a peek at some rare PDA between the Scooby Doo co-stars.

And on Tuesday, for National Selfie Day, Gellar joined in on the public displays of romance by posting an endearing snap of herself kissing Prinze Jr. “Did someone say national #selfie day?? I got this!” she captioned the swoon-worthy photo of the duo from a fun day in the sun.

Whether or not they like to flaunt it, this hot couple has definitely still got it.
