Blake Lively and Ryan Reynolds treat their daughters to play date with Bradley Cooper's daughter

They're some of the most famous parents in Hollywood.

So, it's a no brainer that actress Blake Lively and her husband Ryan Reynolds would set up a play date for their eldest daughters, James, 5, and Inez, 3, with none other than Bradley Cooper's 2-year-old baby girl, Lea.

The parental trio met up on Saturday afternoon at Cooper's NYC apartment.    

Play date: Blake Lively was seen leaving Bradley Cooper's apartment in NYC following play date between Cooper's daughter and Lively's two daughter

Dad's here: Lively's husband, Ryan Reynolds was spotted leaving the apartment, as well, carrying their eldest child James

Brad and Lea: Bradley and 2-year-old Lea followed Lively and Reynolds to a nearby vehicle

Blake was seen cradling Inez in her arms as they made their way towards a nearby vehicle. 

Lively, known for her fashion sense, donned a black, floppy hat that featured a thin, brown leather band.

Her signature bright, blonde hair flowed out from underneath her hat and onto her navy blue wool trench coat and striped scarf.

The coat covered up the majority of Lively's black and white floral tunic, which she paired with black jeans that were tucked into patterned combat boots.

Inez, sporting a bright red star patterned onesie, rocked some major bed-head as she clung onto her superstar mamma. 

Ryan followed closely behind his wife of 7-years with their eldest daughter James. 

Never off duty: Blake and Ryan are full-time parents, always putting family before their careers

Take a hike in Chanel boots like Blake

As much as we love our Jimmy Choos and Christian Louboutins, at this time of year you won’t find us slipping on anything but boots to complete our looks. It’s just too darn cold!

But with the market offering a myriad of boot alternatives you won’t have to compromise on style. Take Blake Lively as a prime example, who we spotted wearing a Chanel pair when out with her family in New York.

The French fashion house has jumped on the bandwagon and produced their own version of the trendy hiker boot that still features their signature quilting - just this time they’ve thrown in some corduroy too.

Reynolds showed off his muscles in a tight-fitting grey long-sleeved top that he styled with black sweatpants. 

Atop his head was a brown, tweed flat cap that allowed him to pull off a nerdy-chic look in conjunction with his black RayBan eyeglasses. 

James looked incredibly cute in a My Little Pony onesie with funky rainbow detailing.

Brad swooped up behind the couple with baby Lea who was busy sucking her thumb.

The 2-year-old looked cozy in a Polarn O. Pyret vest, camo green top, and a pair of light-wash denim jeans.  

Cooper, with a backpack on his back and blue-tinted sunglasses on his face, looked more than ready for dad-duty. 

Surprise: The couple announced their third pregnancy to the world when Blake arrived to the premiere of Reynold's film Detective Pikachu rocking a noticeable baby bump

Smile: Blake and Ryan beamed over the reaction to their shocking announcement 

He wore a black wind-breaker coat paired with charcoal grey sweatpants.  

Bradley and his baby mama and ex, Irina Shayk, share Lea and agreed to fifty-fifty custody in the Summer of 2019.

One stipulation was that Brad would have to relocate to NYC permanently so the custody agreement could play out.

Cooper split from his model girlfriend in early 2019, after four years together. 

Luckily, The Hangover star has local parent friends like Blake and Ryan to make him feel right at home in the Big Apple.   

Blake and Ryan welcomed their third baby girl into the world in August of 2019.

The couple had successfully kept their newborn out of the public eye since Blake gave birth late last summer.   

Family: In 2018, the trio were a happy family while attending the 75th Venice Film Festival in Italy

She broke her pregnancy news back in May as she showed off her baby bump at the Detective Pikachu premiere in Hollywood after also keeping it a secret.

She obviously loves being a parent to daughters James and Inez as she told Allure in 2012: 'I’ve always wanted a big family. Oh, I’d love 30 [children] if I could.'

And in 2017, she spoke to PEOPLE about her parenting style, saying: 'I think it’s hard to slap labels on any parents because it’s just so tricky.

'It’s like every moment you’re figuring out what the heck you’re doing. You think, "Ooh, should I be more strict, or should I be more I don’t know, emotional?" Or whatever it is.
