So, you’re here because you need to know the exact age of Bradley Cooper’s daughter, right? Maybe you’re filling out a very specific trivia card, or perhaps you’re just deeply invested in celebrity offspring birthdays. Either way, welcome to the investigation, where the only thing harder to pin down than her age is whether her dad’s beard is for a movie or just for Thursday.

The Short, Sweet, and Slightly Goosebump-Inducing Answer

Bradley Cooper’s daughter, Lea De Seine Cooper, was born on March 21, 2017. That makes her currently seven years old as of this writing. Yes, a whole seven trips around the sun for a kid whose dad once stared at a raccoon’s butt on a spaceship and made us all cry.

But here’s the kicker: she was born in a New York City birthing center, not a hospital. That’s right—Bradley and his then-girlfriend, model Irina Shayk, went full “natural vibe” for her arrival. I imagine Bradley pacing in hemp sandals, nervously whispering, “Is this the part where I cut the cord with my bare teeth?”

Wait, Why Do I Care About This?

Probably because Lea doesn't have an Instagram account, so her age is a fun little mystery we solve using math and paparazzi photos. Her parents are fiercely protective of her privacy, which means every glimpse of her—usually hiding behind Bradley’s beard at an airport—feels like spotting Bigfoot if Bigfoot wore miniature overalls.

For the record, Bradley once said in an interview that he loves being a dad so much it made him “weep in the shower.” Not an exaggeration. He told People magazine that fatherhood “rewired his brain.” I’m pretty sure my brain rewired after I spent three hours trying to assemble a toy kitchen, but okay, Bradley, you’re the star here.

The Celebrity Math Equation

If you’re doing the math, here’s the surprising part: when Lea was born, Bradley was 42 years old. Which means he’s now 49. That’s a whole seven-year age gap between him and his daughter, which is basically the same time gap between me and my ability to remember where I left my keys. He’s also best friends with Lady Gaga, so Lea has probably been serenaded with “Shallow” during bath time. Imagine that for a lullaby.

And because this is celebrity logic: Lea’s middle name, “De Seine,” is a nod to the French river. Yes, her name literally means “The Seine.” Irina Shayk is Russian, but they went with French river vibes because why not? Celebrity babies have names that sound like fancy perfume brands—while my daughter is named after my grandmother’s cat.

What’s Next for Lea De Seine?

At seven years old, she’s probably in second grade, learning subtraction and why Daddy can’t just Snapchat the paparazzi away. The good news? Bradley and Irina still co-parent like pros, even after their 2019 split. They’ve been spotted taking her to playgrounds and museums, looking every bit the boring, normal family you’d ignore at a Starbucks—if Bradley’s jawline didn’t scream “I invented eye contact.”

So, to answer your question: Lea is seven. She’s old enough to argue, young enough to still think her dad is remotely funny. And considering her dad is a four-time Oscar nominee who once locked himself in a trailer to cry for three weeks practicing a role, the real question isn’t how old she is—it’s how much therapy she’ll need. Kidding! (Mostly.) She’s probably just fine, eating organic snacks and wondering why everyone on the street keeps yelling “Hey, isn’t that Rocket Raccoon’s dad?”

Now go forth, armed with this knowledge. Use it wisely. Or, you know, for your next trivia night where you finally beat your uncle who thinks LeBron James’s daughter is the same age.
