While J.J. and Reid's friendship might have always had romantic undertones, A.J. Cook and Matthew Gray Gubler appear to really be ... just friends. In fact, during a 2015 interview with Glamour, Gubler said Cook was "like a sister" to him. It also helps, of course, that each of them have their own separate love interests.
Cook has been married to her husband, producer Nathan Andersen, for almost 20 years (via Paramount+). The pair first met in college at Utah Valley University and have two sons, Mekhai and Phoenix. Mekhai appeared alongside his mom on a number of episodes of "Criminal Minds," playing J.J.'s son, Henry.
While Gubler appears to be single today, he has in the past been linked to stars like Kat Dennings and Taylor Swift, both of whom would have made incredible "Criminal Minds" guest stars, we have to say (via Distractify).
