Another win for Poor Things came in costume design with Holly Waddington replicating her Bafta win. She looks amazing in a dress with VERY puffy sleeves, inspired no doubt by the designs she came up with for Emma Stone.

Where is her Oscar going to go?

“My other awards are on the kitchen table at the moment (she also won the Bafta)” but she says she’s not sure where the Oscar is going to go yet.

Speaking of working with director Yorgos Lanthimos, she says: “His work is so of our time, his voice is so unusual, he makes very challenging, thoughtful and brilliant work. He’s very bold and encouraging.”

“I’m most inspired by the every day things in life,” she says.

And her favourite costume? “I love the lobster tail she wears in the house!”

The winner of the documentary short film award is The Last Repair Shop.

This tells the story of four craftspeople, who help repair musical instruments to ensure no student is deprived of the joy of music.

It also looks at all the many benefits of making music, including how it can relieve stress and even be an escape from poverty.

Ben Proudfoot and Kris Bowers collected their Oscars, with Bowers calling those in the film "heroes", adding: "You are thanked and you are seen."

"John Williams inspired me to become a composer," he said. "Music education isn't just about creating incredible musicians, it's about creating incredible humans."

Turning to non-fiction, the nominees for documentary short film are:

• The ABCs of Book Banning
• The Barber of Little Rock
• Island in Between
• The Last Repair Shop
• Nǎi Nai & Wài Pó

Takashi Yamazaki, Kiyoko Shibuya, Masaki Takahashi and Tatsuji Nojima took to the stage to claim their visual effects Oscars, clearly delighted with their win.

"We did it!" they said.

Set after World War II, this film sees Japan, already devastated by the war, in the midst of a new crisis battling Godzilla.

The citizens have to battle the fearsome creature after the government refuses to help.

Repeating its Baftas success, director and writer Cord Jefferson picked up the award for best adapted screenplay. It was adapted from Percival Everett’s novel Erasure and is about a black writer who is disillusioned about publishers only wanting stereotypical black stories.

“There’s a Victor Hugo quote,” Jefferson says. “It’s ‘nothing is more powerful than an idea whose time has come’... to be here now and to receive this kind of response feels incredibly surreal, I’m so grateful for it. We didn’t have a huge marketing budget, we relied on word of mouth a lot.

“Hopefully the lesson here is there’s an audience for things that are different and a story with black characters that’s going to appeal to a lot of people doesn’t need to take place in a plantation, on a project, doesn’t need to have drug dealers or gang members in it. It’s important to show diversity within diversity. It’s important to me to recognise that no one black person contains the totality of the black experience.”

Jennifer Lame has won her first Oscar for film editing Oppenheimer.

"Christopher Nolan. I was so terrified when I was hired and I know you took a huge risk on me," she says in her acceptance speech.

She thanks him for instilling confidence in her and adds that it was so exciting to work together.

Oppenheimer is the most nominated tonight with 13.

With 13 nominations, Christopher Nolan's three-hour epic, starring Cillian Murphy, is about the father of the atomic bomb, the enigmatic US physicist J Robert Oppenheimer.

Oppenheimer’s deadly work helped change the course of World War Two, and Nolan told BBC Culture editor Katie Razzall: “He gave us the power to destroy ourselves - and that had never happened before.”

Looking pretty in bubblegum-pink ruffles and drapes on the carpet earlier was Ariana Grande, who's wearing Giambattista.

Grande just about made it in time after posting an Instagram with the caption "traffic".

Robert Downey Jr thanks his terrible childhood and the Academy "in that order" as he collects his award for best supporting actor in Oppenheimer.

He thanks his wife, his stylist and, as is a trend this evening, his publicist.

"I needed this job more than it needed me and I stand here a better man," he says.

He tells the audience that the work they do is "meaningful" and "powerful".

Best original screenplay was won by Anatomy of a Fall, written by Justine Triet (who is also nominated for director), and her partner Arthur Harari.

Speaking about the more international films at the Oscars now, Triet said: “Films can cross borders and if it can resonate with people all over, what’s at stake is an international relationship. And it’s a very European film. Foreign films are finding more of an audience in America. It’s a beautiful thing to witness.”

As anyone who has seen the film, Bacao Rhythm and Steel Band’s version of 50 Cent’s P.I.M.P. plays a big role.

But Triet reveals it wasn’t the first choice. “We asked Dolly Parton for Jolene who refused to give us the rights.” Dolly’s loss is 50 Cent’s gain!

It’s mother’s day, so for any American Pie fans out there I managed to grab a chat with Stifler’s mom, the original MILF.

On her way into the Vanity Fair party Jennifer Coolidge gave me her tip for the best way to work the room at the hottest night in Hollywood.

“I spent a lot of time eating last year” she explains “so this time I ate before, so I can meet all the people I haven’t met yet and chat with my friends, and hopefully the night doesn't end til tomorrow morning”.

It's time for the actor in a supporting role award.

The nominees are:

• Sterling K. Brown for American Fiction
• Robert De Niro for Killers of the Flower Moon

• Ryan Gosling for Barbie
• Mark Ruffalo for Poor Things

Actor and producer Michael Douglas just stopped for a chat with me on the red carpet, and told me he's been giving advice to Joe Biden lately about how to be president.

“But the problem is, I know how the script ends... he doesn’t!” he tells me, before walking off with a “fingers crossed”.

So, I guess we can conclude he’s not backing Donald Trump in the upcoming presidential election.
