Jon Hill is not happy that ex-wife Jaclyn Hill has a new boyfriend, and he's letting the world know.
Yesterday, Jaclyn confirmed her new relationship by posting a cute hand-holding photo online, captioned with love heart emojis.
Jon then decided to have a crack at shading her photo by posting his own version... only his was with a dogs paw.
The most awkward part was when a fan asked Jaclyn to explain the post. "No explanation," she responded. "Just let him be petty!"
OHHH boy. Things are definitely getting messy now.
