The Celebs Turning a Year Older on April 12 — Wanna Guess Who?

David Letterman basically changed late-night TV forever starting in 1982 with his show. He’s funny, smart, and still making waves with his Netflix show. Fun twist: he once got kicked off his college radio for messing around with classical music. Classic Letterman move.

You know him as Al Bundy and Jay Pritchett—two of TV’s best dad roles. Ed O'Neill has a secret weapon though: he's got a black belt in Brazilian Jiu-Jitsu. Before acting took over, he almost played pro football. Imagine Al Bundy on the field!

Andy Garcia - the guy from Ocean's Eleven and The Untouchables who’s got that smooth vibe. Here’s a wild fact: he was born with a tiny conjoined twin on his shoulder (yep, really!), and don’t worry, it was taken care of.

Claire Danes started out dancing before switching to acting—and good call! She won an Emmy for Homeland and was that unforgettable teen in My So-Called Life. Dance moves turned into acting chops, and we love it.

Saoirse Ronan is basically perfect at acting. Her name means "freedom" (pronounced "Seer-sha"), which suits her star power perfectly. She's snagged Oscar nods and keeps winning hearts everywhere she goes.

Brendon started off as a guitarist but stole the spotlight as the amazing singer of Panic! at the Disco. Those hits like "I Write Sins Not Tragedies"? He’s the reason you can’t stop singing. Oh, and he even did Broadway—because why not?

Vince Gill's voice and guitar skills are next level. He’s got more Grammys than you can count (22!) and even opened for the rock band Kiss… in bluegrass style. That’s mixing things up in the coolest way.

Jennifer Morrison made us love her as Dr. Cameron on House and Emma Swan in Once Upon a Time. Little secret: she was on Sports Illustrated for Kids at just 10 years old—hanging out with Michael Jordan! Pretty cool, right?

Brooklyn Decker went from Sports Illustrated covers to Netflix hits like Grace and Frankie. Guess what? She’s named after a horse called Brooke—because why not name your kid after your best friend’s favorite horse?

Jessie James Decker made her first stage appearance at age two (yeah, really) and won her first talent show at nine. She’s got the voice, the style (hello, Kittenish fashion), and a reality TV life that keeps us all entertained.
