Brian Austin Green has had enough of the drama, and he's speaking out. The actor responded to his ex-girlfriend Vanessa Marcil, who recently claimed he didn't co-parent their son, Kassius. Brian made it clear that he disagreed with her recollection of his participation in parenting. He stood up for his ex-wife, Megan Fox, as well.
The drama started after Venessa answered a recent question on her Instagram Stories.
A follower asked Vanessa about her co-parenting situation with Brian and how that worked when Kassius, now 20 years old, was younger.
Answering the question, Vanessa said, "We didn't & don't co-parent. I raised my son alone," according to E! News.
Somehow Brian saw her answer, and he fired back against her claims that he was absent.

Brian answered back by sharing a screenshot of Vanessa's claim, and it was evident that his recollection was very different. He wanted to make his stance clear.
"So, I can't tell you all how frustrating it is to read continued lies from a 50+ year old woman on social media like she is still in high school," he wrote.
'She has never in her life been someone to walk the walk. Talk is cheap.'
He then mentioned his ex-wife, Megan, with whom he shares three sons: Noah, 10, Bodhi, 9, and Journey, 6, saying she was also very involved in raising Kassius.
"Megan and I bust our a–es to give Kass a well rounded childhood since his mom was rarely there," Brian wrote.
"I'm assuming that's why she posts so much of him now. When will she just GO AWAY."
The drama between Brian and Vanessa has bubbled up several times over the years, but so has their support for each other.
According to E! News, in 2018 Vanessa made another claim against Brian and Megan, saying they had "completely cut Kass out of their lives" and claimed that her son was "truly heartbroken" over the alleged situation.
But things seemed to be better between the exes over the past few years. Vanessa supported Brian when he was competing on Dancing With the Stars, and her son had a good time visiting Brian when he was in Canada.
Kassius is 20 years old now, so there's no doubt he's watching the drama unfold on Instagram.
What is interesting is that Kassius doesn't follow his dad or his mom on Instagram. He does, however, follow Megan and his dad's current wife, Sharna Burgess, whom he met while competing on Dancing with the Stars and now shares a 7-month-old son.
