Florence Pugh quickly helps Emily Blunt after button pops open on suit

Florence Pugh came to the rescue of Emily Blunt following a major wardrobe malfunction at a photocall for their new movie.

The pair were walking the red carpet in London for a photocall ahead of the premiere World War Two biopic Oppenheimer when they stood to pose for some snaps.

At first, it all appeared to be going swimmingly, the two actors standing alongside one another while the paps got their pics.

However, seconds later, disaster almost struck, with Blunt's jacket popping open, revealing part of her bra.

While this could have been another Janet Jackson moment, Pugh was quick off the mark to help her pal out.

Grabbing hold of her blazer, she pulled the lapels together, keeping her co-star's modesty intact.

Since the clip was shared widely on social media, fans have been full of praise for Pugh and her quick thinking.

Taking to TikTok, one user said: "This is adorable, they looked like little girls for a second helping each other. What a beautiful moment captured."

Another jumped in: "This is the cutest thing I've ever seen."

"That was such a sweet and genuine reaction from both of them," put a third.

While someone else added: "There are few things more powerful than women supporting women."

The following day, there was a different vibe to proceedings, with the shadow of the actors strike casting a pretty dark shadow over the event.

And it ended with the film's cast, including Blunt and Cillian Murphy walking out on it.

The news was confirmed by the director of the long-awaited movie, Christopher Nolan, explaining that they left as part of the union strike.

“You’ve seen them here earlier on the red carpet,” Nolan told the cinema’s audience on 13 July.

“Unfortunately, they’re off to write their picket signs for what we believe to be an imminent strike by SAG-AFTRA (Screen Actors Guild - American Federation of Television and Radio Artists), joining one of my guilds, the Writers Guild, in the struggle for fair wages for working members of the unions, and we support them.”

Ahead of the premiere, Blunt had told Deadline that she and the rest of the cast would be leaving if a walkout was approved by their union.

She said: “I think right now we are just sort of - I hope everyone makes a fair deal and we are here to celebrate this movie. "And if they call [a strike], we’ll be leaving together as cast in unity with everyone. … We are gonna have to. We are gonna have to. We will see what happens. Right now it’s the joy to be together.”
