While director Greta Gerwig's 'Barbie' performs well at the box office, inching towards the $1 billion mark, Ryan Gosling, who played Ken in the film, has sent the director a flash mob of Kens to celebrate the movie's success and her 40th birthday.

On the official TikTok account for the 'Barbie' movie, a video was shared revealing how a full pink Barbie-themed flash mob was used to surprise Gerwig on her special day.
