It’s a girl for Jessica Capshaw!

The Grey’s Anatomy star welcomed her fourth child, daughter Josephine Kate Gavigan, on Monday, May 2, she announced on Instagram.

“I am endlessly grateful for her safe arrival and my heart is so full of love that it threatens to burst,” Capshaw captioned a photo of her newborn. Gavigan added, “Welcome to our newest & sweetest little one. Our hearts are bursting in so many ways.”

The actress and husband Christopher Gavigan, co-founder of the Honest Company, revealed in December that they were expanding their family.

“This year our family has further reason to broaden our smile … baby number four is on the way!! I am a lucky, lucky girl…” Capshaw, who is already mom to son Luke Hudson, 8, and daughters Eve Augusta, 5, and Poppy James, 3, said at the time.

Capshaw recently spoke to PEOPLE about pregnancy the fourth time around.

“I’m [due] any minute now,” she said while attending the Annual H.E.A.R.T. Brunch. “I’m an ‘any-minuter.’ I’m the person that makes people very nervous! I’ve had more people offer to help me downstairs today than my whole life.”

The actress also shared that she was milking her precarious state as much as possible while she still could.

“I was with my girlfriend at a restaurant and we didn’t make a reservation and there was a wait for 30 minutes,” she said, adding that the manager offered them a table after just a minute of waiting.

“My girlfriend looks at me and is like, ‘Man, this whole Grey’s Anatomy thing totally pays off.’ “

She added, “I was like, ‘Guess what! Don’t think that has anything to do with it!’ I’m a liability looking this pregnant, standing at the front of a restaurant waiting for a table. I have a couple more weeks to enjoy the front-of-the-line status.”
