If they said younger than she is, I would have said “good job, kids!” But, this is ridiculous! LOL!

Kristen Bell hit the big 3-9 today (Thursday- HAPPY BIRTHDAY!) But, it turns out if you ask her children, your jaw may drop!

She posed the question to the little ones on Instagram and they basically said  she’s a senior citizen.

My kids are kind. I dont care if they cant do math ???????????? (For my #armcherries : #fastmath is overrated.)

Her 4-year-old daughter Delta replied, “Six…fifty,”finally landing on 63. Bell’s 6-year-old daughter Lincoln put mom in the nursing home by guessing 89. And of course, hubby, Dax Shepard didn’t make things better, “I think a safe bet, somewhere in the middle of those two guesses, so…71? Is that right?”

I think it’s safe to say though, this is just the most perfect little family there is.
