Ryan Gosling Surprises Greta Gerwig With a "Barbie" Flash Mob of Kens For Her Birthday

There's no doubt Greta Gerwig was feeling the Kenergy on her 40th birthday, thanks to Ryan Gosling. On Aug. 4, the official "Barbie" Instagram shared a video of Gerwig receiving a special surprise from Gosling in the form of a flash mob of Kens and Barbie. The movie's director can be seen laughing and shedding a few tears as she's suddenly bombarded by a group of men dancing their hearts out to "I'm Just Ken."

The video begins with the Kens dancing and lip-synching to the "Barbie" power ballad "I'm Just Ken" before a group of Barbies crash the party with their own dance number. As the Barbies run into the room, the music switches to Dua Lipa's "Dance the Night Away," which sparks an exuberant dance party for the entire flash mob. At the end of their performance, all of the dancers shout, "Happy Birthday, Greta!"

Near the end of the video, Gerwig hugs all of the dancers, and someone off-camera asks the director if she knows who planned the musical surprise for her. "I have no idea," she responds. "Think of the bagpipes," they tell her, reminding Gerwig of the time Gosling sent a bagpiper to the "Barbie" sleepover to play for his costars.

"As Kens know… Sometimes the only way to express your feelings is through song & dance!" the Instagram's caption reads. "Ken Ryan sent these special Barbies and Kens to start Greta's birthday with all the feelings!!"

Gerwig's 40th birthday was already guaranteed to be an unforgettable one thanks to the huge year she's having. In addition to "Barbie" having the biggest opening weekend ever for a movie from a female director (and becoming a certified blockbuster), she also welcomed her second child earlier this year.
