Brian Austin Green and his 17-year-old son appear to be working on mending their estranged relationship.
The "Beverly Hills, 90210" star's son, Kassius Marcil-Green, visited his dad at work on Tuesday where they're filming the reboot in Canada.
His teen son, who he shares with ex Vanessa Marcil, was captured behind-the-scenes by Green's co-star Shannen Doherty.
Marcil later shared it on her personal Instagram page with the touching caption, "@kassius_marcil_green visiting his dad in Canada."
This comes just months after she claimed Kassius has no relationship with his father or his stepmom, Megan Fox.
Marcil took to social media to unload on the TV star, saying Kassius got "cut out" of his dad's life.
She also claimed Fox tried to get full custody of Kassius over 10 years ago.
“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,” Marcil said at the time. “They lost that case & a civil case asking me for 200,000.”
In the heartbreaking post she stated that Kassius had absolutely no relationship with Green and Fox, and had never even met their youngest child. Marcil also claimed Kassius "is not allowed" to know where his other family lives.
It appears that's water under the bridge now, because Kassius couldn't contain his excitement when he was packing to see Green.
Sharing a post before he flew out, he showed off his giant suitcase signifying he may be spending more than a few days with Dad.
"Just some pictures I took before I left for Canada (My bag is massive)," he wrote.
Before their fallout, Green and his son were thick as thieves. He even served as his dad's best man when he wed Fox in 2010.
In the photo above, a young Kassius can be seen holding his stepmom's hand as the trio ran errands around Los Angeles.
Green and Fox share three kids together -- Noah, 6, Bodhi, 5, and Journey, 2.
Hopefully this reunion with extend to the entire family.
