Rob Brydon has become the ultimate scene stealer in the hotly anticipated Barbie as cinemagoers have been left 'freaking out' and applauding the actor's cameo.

Barbie, which stars Margot Robbie as the titular doll alongside Ryan Gosling's Ken, is a bright and bubbly toy-meets-real-world tale that has literally painted cinemas around the world pink.

The official synopsis says: "After being expelled from Barbieland for being a less than perfect-looking doll, Barbie sets off for the human world to find true happiness."

The two stars are also joined by the likes of Will Ferrell, Michael Cera, Sex Education star Emma Mackey and Shang-Chi and the Legends of the Ten Rings actor Simu Liu.

The feature-length comedy also has its fair share of celebrity cameos, including the Gavin & Stacey star, who confirmed his involvement fairly recently.

Brydon's cameo has become one of the biggest talking points from the film on social media, after film fans rushed to the cinema to watch Barbie on Barbenheimer day.

One cinemagoer tweeted: "Goes without saying that Rob Brydon had my favorite BARBIE cameo."

Another fan sent a tweet to Brydon's account and gushed: "I literally was freaking out seeing you in the movie!! Such a fun cameo!"

A third person penned: "I loved Barbie but more importantly I loved Rob Brydon as sugar daddy ken and that was enough for me to give the film a 10."

Meanwhile, one film fan wrote: "We saw Barbie tonight and when Rob Brydon came on screen for all of two seconds the whole cinema whooped and applauded."

One more cinemagoer confessed: "ROB BRYDON IN THE BARBIE MOVIE???????????? I actually leapt out of my seat."

Brydon joined the stars at the London premiere on 12 July where he revealed the adorable way he got the role and gushed about Robbie, who just so happens to be a huge Gavin & Stacey fan.

"I had a message a few years ago that Margot Robbie was a big fan of Uncle Bryn and would I record a message for her birthday," he told virginradio.co.uk.

"So I recorded a video for her. I think maybe this part is her way of saying thank you.

"I said, ‘Hello Margot. I've loved you in all your films and I'll tell you for why...’ So when I met her on the set, she said, 'Ah, thank you so much for that message…' So that was quite nice.”

Following the premiere, Brydon urged cinemagoers not to blink when watching the film. In a tweet shared from his account on 13 July, the Welsh actor said: "Had a great time at the Barbie premiere celebrating my pivotal role as Sugar Daddy Ken. When you go to see this amazing film please don't blink."

Long live Sugar Daddy Ken!
