Blake Lively Gave Her 'Travelings Pants' Sisters A Huge Role In Her Baby's Life

Still no word on whether or not the pants fit the baby.

In the book that birthed the beloved "The Sisterhood of the Traveling Pants" film, Tibby (Amber Tamblyn), Carmen (America Ferrera), Lena (Alexis Bledel) and Bridget (Blake Lively) were all born weeks apart by mothers who became best friends in their birthing class. That reality didn't exactly pan out in real life -- neither did the perfectly form-fitting magic pants, probably -- but the four actresses were just connected for life by the birth of a baby.

Tamblyn revealed on VH1's "Big Morning Buzz" on Thursday (April 9) that she, Ferrera, and Bledel all act as godmothers to Lively's baby with Ryan Reynolds, a little girl named James. Nick Lachey brought up the rumor during a round of rapid-fire questioning, and Tamblyn -- who previously told People that Lively hid James' birth from her until she visited her home to look at "wallpaper" -- was happy to officially announce the news.

"Yes, that is a fact," Tamblyn said as the audience freaked out, because babies.
