The couple is already parents to a 4-year-old daughter, whom they welcomed in 2019. Slater is also dad to daughter Eliana, 22, and son Jaden, 25, whom he shares with ex-wife Ryan Haddon.

At the fourth and final season premiere of Mr. Robot in October 2019, Slater opened up to PEOPLE about welcoming his daughter with Brittany.

“It’s cleaning those bottles — there’s so many pieces to break down with that stuff, it’s a milestone to get through it,” he told PEOPLE at the premiere in New York City.

“An official milestone is that she’s actually starting to really acknowledge us and smile, which is a big deal,” Slater said.

“Before, it would just be this involuntary thing,” he continued. “Now, she sees and smiles, and that’s a beautiful milestone.”

After three years of dating, the couple secretly tied the knot at a Miami-area courthouse in December 2013.

The dad of three appeared on The Late Late Show with James Corden in 2019, where he jokingly discussed how “complicated” parenting has become since he last had a newborn, bringing up his bottle struggles with the host.

“I thought your kid could get a couple of germs and be fine, build up the immune system. But now you have to wash everything,” said Slater.

“The bottles, they break down into eight different pieces, and it’s a puzzle you have to put together,” he quipped. “I got dish gloves on, I’m just washing these bottles.”
