"It's business as usual for them," the source said. "They're committed to their business and to their future together as they work together on the show."
Court documents obtained by ET show that 35-year-old Tarek is requesting joint legal and physical custody of his and Christina's children, but is requesting spousal support from his estranged wife. Tarek is also asking that Christina pay his attorney's fees, and that the court terminate its ability to award alimony to her.
Our source called Tarek's request for spousal support "laughable."
"They share everything, so it's laughable," the source said, adding, "they're sharing custody of the children, and their number one priority is raising their children together, and doing what's best for the family."
Along with Christina, Tarek also appears to be putting their kids first despite the divorce drama. Last week, he posted video of himself dancing with Taylor and Brayden to Maroon 5 and Kendrick Lamar's "Don't Wanna Know," and tagged Christina in the post.
"#Dancing with the #stars... No #dancing with my #stars!!" he gushed. "Nothing like coming #home to these two. #luckiest man #alive. @christinaelmoussa."
