Kristen Bell & Daughters Celebrate Dax Shepard's 'Sobriety Birthday'

Kristen Bell and her daughters are helping Dax Shepard celebrate a major milestone!

The 40-year-old actress took to Instagram on Tuesday (September 1) to share a handwritten by one of their daughters on the 45-year-old actor’s “sobriety birthday.”

Kristen and Dax share daughters Lincoln, 7, and Delta, 5.

“Today is my husband’s 16th sobriety birthday. My daughter woke him up with this sign, and a sketch of the one and only Ronald Weasley(absolutely random, and also perfect),” Kristen wrote. “Happy birthday Daxy. Thank you for dedicating your life to the hard and wonderful work of sobriety, so that we could share it with you. Xo K, L & D”

Dax officially got sober in September 2004. He started dating Kristen in 2007, and she has been a extremely proud of Dax‘s sobriety journey.
