It’s a baby boom! Everyone loves hearing about new babies - especially when they are born to celebrities. So whose families have grown this week?

Soleil Moon Frye and Melissa Rycroft added to their families and Alexis Bledel confirmed she’s a first-time mom - and it’s boys all around!

In extremely surprising news, Bledel’s rep confirmed that she and her actor husband Vincent Kartheiser welcomed a baby boy last autumn.

The new addition to their family probably would have remained a secret if not for the big mouth of her “Gilmore Girls” co-star Scott Patterson, who revealed that she was a mother in an interview with Glamour magazine yesterday about their series’ Netflix reboot.

“She’s really blossomed as a woman and now she’s a proud new mother and married and happy,” Patterson said. “We’re comparing notes because my son is about a year and a half older than her young son. I’m showing her photos and videos and what to expect.”

This is not the first time that the very private couple - who began dating in 2012 after meeting on the set of “Mad Men” - has kept a major secret. Two months went by before it was disclosed that Bledel, 34, and Kartheiser, 37, had wed in June 2014.

“Punky Brewster” star Frye and her husband of 17 years, Jason Goldberg, welcomed son Story into the world May 16 at 5:16 p.m. The couple’s fourth child weighed 9 lbs., 10 oz. and measured 20.5 inches long at birth.

Thirty-nine-year-old Frye devotes her life to her children and helping mothers just like her by blogging and sharing ideas for DIY projects. The author also co-founded The Little Seed, which sells eco-friendly and organic products for children, and partnered with Seedling to sell activity kits for kids.

Story joins big sisters Poet Sienna Rose, 10, and Jagger Joseph Blue, 8, and older brother Lyric Sonny Roads, 2.

 Welcome to the world our sweet baby boy Story...
