Surprise! Amber Tamblyn's daughter with husband Davis Cross will not be named Dauphinoise Petunia Brittany Scheherazade Von Funkinstein Mustard Witch RBG Cross Tamblyn-Bey Jr., as the actress previously suggested she might be.

Instead, the Sisterhood of the Traveling Pants star gave her baby girl a more classic pick: Marlow Alice Cross.

Tamblyn announced the name by posting a very special letter addressed to little Marlow on Instagram. The letter wishes the little girl a happy birthday from former First Lady and Secretary of State Hillary Clinton.

"Crying now," Tamblyn wrote in the post. "A letter from one spectacular woman who has lived so much to another who has only just begun."

In the letter, Clinton wished Marlow a "lifetime of amazing accomplishments and adventures, full of love, learning, and friendship." And even better, the letter was a surprise! Tamblyn hadn't been expecting to hear from the former presidential candidate.

"My heart is as full as this diaper I'm about to change," Tamblyn quipped on Instagram. "Thank you, Hillary, grandmother to us all."
