Jennifer Love Hewitt pregnant with baby No. 3

Jennifer Love Hewitt has another baby on the way.

The 42-year-old actress shared the happy news in an adorable social media post on Tuesday, writing, "Oh baby! We have another one on the way. So excited to finally share this news with all of you."

This will be the third child for Hewitt and her husband, Brian Hallisay. The couple, who have been married since 2013, are already parents to 7-year-old daughter Autumn James and 5-year-old son Atticus James, whom Hewitt said are both "so excited" for the new addition -- even though it did come as a surprise.

"We had always been open to a third, but definitely didn't think in the crazy year that the entire world was having that it would necessarily be this moment," the "9-1-1" star told People.

"I feel like we've been able to so far raise two really special kids who will be great role models," Hewitt added. "This has been such a pleasant, beautiful, surprising gift in this time to be able to get to do all that again with another little human."

While Hewitt admitted she loves "the experience" of being pregnant, she said there are no plans for her to have more beyond baby No. 3.

"I don't think I could do another one," the "I Know What You Did Last Summer" star said.
