It’s Dax Shepard‘s big day!

The CHiPs actor is getting some love from his wife Kristen Bell in honor of his 42nd birthday on Saturday (January 2).

“It’s my favorite day of the year!” the 40-year-old Veronica Mars actress wrote on Instagram. “When I get to celebrate the birth of my very favorite human on earth, and spoil him till he rots! The one who’s commitment to growth is astounding, who’s honesty is admirable, and who makes me laugh more than anyone. I love u so dearly, @daxshepard 💥🦄🎂🎊🎈🎉”

Kristen and Dax have been married for seven years, after tying the knot in a super low-key courthouse ceremony back in October 17, 2013. They share two daughters: Lincoln, 7, and Delta, 6.

Dax recently opened up relapsing after 16 years of sobriety.
