Late last year, Brian Austin Green’s ex Vanessa Marcil accused him of leaving their 17-year-old son Kassius Marcil-Green in the lurch and ditching him in favor of his “new” family with Megan Fox, who he married in 2010. Brian and Megan share three sons: Noah, 6, Bodhi, 5, and Journey, 2.

After issuing a series of angry social media posts in which Vanessa accused Brian and Megan of never spending time with Kassius, she went silent.

In one post, she said: “12 years ago I was served legal papers and then spent 8 years+ defending myself and my son in custody court in response to his father & his stepmother trying to get full custody(that means I would have seen my son four days a month) and then asking me to pay them child support,” she wrote at the time. “They lost that case & a civil case asking me for 200,000. I never spoke publicly in order to protect my then young son from hearing anything negative about his father and from paparazzi that used to follow him & terrify him. I had also never asked for child support of any kind and had never tried to take time away from Kass’ dad seeing him. Ever.”

Something must have happened behind the scenes, because Kassius and Megan both joined Brian on-set of Fox’s reboot of 90210, in which he stars. 

Kassius shared images from the set on Instagram Stories, writing: “First day on the set of the 90210 ‘reboot’ and I’m confused in an amazing way.” 

“I’m visiting my dad in Vancouver on the set of 90210. We’re going to be staying here for a bit. I’m here for a week. I think we’re, like, staying somewhere near downtown,” he said. “So if for any reason any of y’all who are out here or live here happen to see me, please say something. I would love to meet y’all. So please, if you happen to see me, don’t get scared and not say anything. Please. I want to meet y’all if I can.”

The teenager then noted how “everyone is cool as s— tho” and posted a snap of him “observing” the shoot. 

Brian and Vanessa got together in the 1990s after meeting on the set of 90210. They were engaged, but never married and split up in 2003. Kassius was born in 2002. 

BH90210 will premiere on FOX on Wednesday, August 7, at 9 p.m. ET.
