After Fox posted a photo of herself in a bikini with her shirtless new boyfriend, Machine Gun Kelly, writing, "Achingly Beautiful Boy... My heart is yours ?♥️?," Green shared a series of photos of his 18-year-old son Kassius from a previous relationship and his three sons with Fox, Noah, 7, Bodhi, 6, and Journey, 4, using the same caption.
“Now we know why she broke up with you. Your children must be more mature than you. Move on,” one user wrote on Green's post, to which the actor replied with a crying laughing emoji.
Another person also commented, "Someone mad Kells would whoop that a** old man."
Green, once again, left a crying laughing emoji. He continued to do so on another comment that read, "It appears @brianaustingreen is setting the stage for a custody battle, and he’s playing the ‘devoted father’ role while smearing the mother of his children, amazing how many people are falling for his little act."
Fox, on her end, is enjoying her time with her new beau. The new couple had a little fun on Instagram on Thursday, posting a video jamming out to the 30-year-old singer's new song, "Concert for Aliens."
