It's official: Amber Tamblyn and David Cross did not name their daughter Dauphinoise Petunia Brittany Scheherazade Von Funkinstein Mustard Witch RBG Cross Tamblyn-Bey Jr.

The actress took to Instagram today to reveal her 1-month-old baby's actual name, and it's a whole lot simpler than the name she teased (see the above very lengthy moniker) in a post announcing their child's birth last month—the Hollywood couple really named their little one Marlow Alice Cross. The news came via an photo of a letter sent to the newborn from Hillary Clinton wishing her a happy birthday.

"The one day I decide to put mascara on Hillary Clinton sends us this letter for our daughter. Crying now," Tamblyn captioned an image of the note addressed to Marlow. "A letter from one spectacular woman who has lived so much to another who has only just begun. My heart is as full as this diaper I'm about to change. Thank you, Hillary, grandmother to us all."

Congratulations again to Tamblyn and Cross on their bundle of joy! We can't wait to see more photos of the cutie.
