Brian Austin Green is calling out Machine Gun Kelly for not being "honest" after the musician claimed he was still in contact with his ex Megan Fox.

Green, who was married to the Jennifer's Body star from 2010 to 2020 and welcomed three children during that time, slammed MGK for his comments disputing claims he and Fox, who is pregnant with their first child together, were not talking after their split last year, per People.

Sources told TMZ last month that the pregnant New Girl actress and the "Lonely Road" singer are "not on good terms" and that "the lines of communication [are] closed" after the on-again off-again couple ended their relationship in November, just weeks after announcing their were expecting their first chid.

Following those reports, the "bloody valentine" rocker called out the narrative that he and Fox were no longer on speaking terms; however, Green seemingly took issue with MGK's stance in a since-expired Instagram Story on Sunday (February 2).

"Bro. Just be honest for once in your life," he wrote. "Stop caring so much about how you're perceived that you will try and drag other people."

This isn't the first time the Beverly Hills, 90210 alum has shared strong words for the rocker. In December, Green seemingly shaded MGK, telling him to "grow up" while admitting he "just [wants] the best for her, the best for the baby, the best for our kids."
