Ryan Gosling lost it when 'Barbie' costar Ncuti Gatwa was announced as the new lead on 'Doctor Who'

• Ryan Gosling was thrilled that Ncuti Gatwa will be the new Doctor on "Doctor Who."
• Gatwa told British Vogue that his "Barbie" costar came "bounding up" to his trailer when the news dropped.

Even celebrities have their fanboy moments.

Ncuti Gatwa — who will be the next actor to play The Doctor on "Doctor Who" — said that his "Barbie" costar Ryan Gosling lost it when Gatwa was announced as the new lead of the long-running British sci-fi TV show.

In an interview with British Vogue, Gatwa said Gosling, who plays Ken in the movie, came "bounding up" to his trailer when the "Doctor Who" news dropped.

" 'Doctor Who' is the coolest show in the world, man!" Gatwa said Gosling told him. "I'm the biggest fan."

Gatwa giggled as he retold the story. "I was like, 'What the hell?' This show has incredible reach."

"Doctor Who" has skyrocketed to worldwide fame after the BBC hit rebooted in the early 2000s, bringing in rising stars like David Tennant, Matt Smith, and Jodie Whittaker to play the titular time-traveling, pacifist alien with hearts of gold.

Gatwa said he was shocked when he found out he'd gotten the coveted role since he'd assumed "there's no way they'll cast a Black man."

"I felt numb," the "Sex Education" star told British Vogue. "And keeping it a secret until the announcement was very difficult. I'd often get a little tipsy in Soho House, make a new best friend in the bathroom, tell them, and run off. Thankfully, it never got out."

And Gatwa said he was overwhelmed by the positive reception to the news of his casting.
