Brittany debuted her baby bump as she turned to the side while standing next to Slater, 54, in a long floral dress at the private screening.

The couple already shares a four-year-old daughter, whose name has not been publicly disclosed.

Slater also has two older children, Eliana, 22, and Jaden, 25, from his previous marriage to journalist Ryan Haddon.

In a previous interview, Slater expressed his joy at watching his youngest child grow, saying, “Before, it would just be this involuntary thing. Now, she sees and smiles, and that’s a beautiful milestone.”

He also joked about the challenges of modern parenting, saying, “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.”

The exciting news comes just three months after revealing Brittany was expecting as they attended the Los Angeles premiere of his film Unfrosted (seen in April 2024)

Slater confessed that the newborn stage is a “constant job” of cleaning and late nights, but he was proud to contribute to childcare duties, saying, “I was able to contribute something, and that I did know how to change some diapers.”

The actor and his wife tied the knot in a secret Miami-area courthouse ceremony in December 2013.

The couple celebrated their engagement with a New Year’s Eve bash in 2012, attended by hundreds of friends and family.

At the time, Slater mentioned that their private wedding ceremony already felt like a wedding, saying, “It kind of already feels like we did the wedding.”

Despite the intimate affair, Christian and Brittany planned a family-oriented event for their wedding later that year, which would be “good, intimate, and small with family members.”
