Sunday will be the first time that the four have celebrated Mother's Day as mothers. They are among dozens of stars who have given birth for the first time this year as Hollywood continues its unprecedented baby boom.

Missing out on the big day are some first-time moms-to-be such as Natalie Portman, January Jones, Ivanka Trump, Pink and Marion Cotillard.

And that doesn't include some experienced celeb moms who are adding to their brood this year, like Kate Hudson, Jennifer Connelly, Jessica Alba, Mel B. and Victoria Beckham.

Happy Mother's Day to them all.
