Reese Witherspoon Gives Sweet Birthday Tribute To 21-Year-Old 'Twin' Daughter Ava

It's hard to believe the celebs we loved in the '90s and early aughts have kids that are just as old as we were back in the day, amirite?!

(And yes, I'm 24 but you guys feel my drift! I feel like I am a mid-forties housewife, always.)

A great example of a celeb who is in her forties but looks like she's 24 is one Reese Witherspoon!

This is your monthly reminder that Reese Witherspoon is 44-YEARS-OLD!
