Mahershala Ali's win for best supporting actor comes just two years after he won the same prize for Moonlight.

His victory for Green Book is the fastest any actor has won the same Oscar twice since Tom Hanks, who won best actor in both 1993 and 1994.

"I feel very fortunate. I feel fortunate to have been nominated," Ali says backstage.

"Any of those gentlemen could've been up here and been deserving. They did wonderful work, beautiful work, work that inspired me. So to be the one that was chosen to get to hold this trophy is not something I take lightly, or take for granted."

Ali also explained just how impactful Moonlight had been in raising his profile.

"The first [Oscar] helped me get Green Book. I wasn't just getting offers like that.

"So to get an Oscar for Moonlight, it changes your profile, it gets you in other rooms, it shines a light on your work.

"You could've been around for 15-20 years and suddenly people notice you."

The final Oscars may have been handed out but the night isn't over yet.

The stars are heading for the Vanity Fair Oscars party.

While Taylor Swift hasn't appeared on the red carpet yet, her stylist gave a preview of her outfit on Instagram.

Spike Lee has been a critic of the Academy in the past, but he warmly welcomes the changes it has made in recent years to diversify its membership

"Here's the thing," he says backstage. "Without April Rain [the founder of the OscarsSoWhite campaign], and Cheryl Boone Isaacs [a former Academy president], I wouldn't be here tonight.

"They opened up the Academy to make the Academy look more like America, so it's more diverse.

"That would not have happened without OscarsSoWhite."

Husband-and-wife team Miley Cyrus and Liam Hemsworth are on the red carpet again, this time at the Vanity Fair party.

Green Book director Peter Farrelly had an interesting strategy when it came to winning best picture.

He employed the same tactic he does with sports teams, which is to hope that if he doesn't think about something, it will happen.

"We were nominated so of course I thought we could win, but we didn't expect it, honestly," he says backstage.

"I kind of block it out, if I watch my football team and I need them to score, if I leave the room, they will. If I'm watching them, they won't.

"So I thought about everything but winning this film, and it worked."

Green Book has attracted a lot of controversy, partly because of reports Don Shirley's family were not happy with how he was presented.

But writer Nick Vallelonga, who discussed directly with Shirley before he died how he wanted the film to be, defended the portrayal.

"We told the story he wanted to tell," Vallelonga tells the press.

"He told me if you're going to tell the story you tell it from me and my father [Tony Vallelonga, the other main character in the film], and also he told me not to make it until after he passed away, so I kept my word."

"The journey has been a very long one," says Alfonso Cuaron of making his film Roma, which netted him three awards tonight including best director.

"Of anything I have ever done, this is the one I expected the least," he says of the Academy recognition.

"This film is not what you'd call 'Oscar bait'. So I'm thrilled this is happening.

"Most importantly, that audiences around the world and the Academy are embracing a character who is a domestic worker from the indigenous background."

Yalitza Aparaicio, who plays the lead role in Roma, had never acted before when she was cast.

Asked how he knew she was right for the part, Cuaron says: "It was completely instinctual. When she walked into the room, I knew it, it was as simple as that."

In the absence of a host, Julia Roberts closed the ceremony.

She did it with a shout-out to A Star is Born actor Bradley Cooper's mum Gloria Campano, who sat with her son in the front row of the audience.

Campano has been a big hit with the twitterati.

You don't even have to have seen The Favourite, it seems, to be utterly delighted for the British star.

Director Peter Farrelly said, when accepting his Oscar for best film: "The whole story is about loving each other despite our differences and finding the truth, that we're the same people."

But Green Book's win surprised many on social media - and it's not getting a whole lot of love.

It's been a really split picture tonight with no single film sweeping the board.

Here are the biggest winners:

Bohemian Rhapsody – 4

Roma – 3

Black Panther – 3

Green Book - 3

All the rest of tonight's winners got one award apiece.

The huge gasp of surprise in the press room when Olivia Colman won best actress earlier was eclipsed only by an even bigger gasp of surprise a few minutes later when Green Book won best picture.

Neither were the favourites in their category. Glenn Close was widely tipped to win leading actress, while Roma was largely thought to have best picture in the bag.

It's possible Roma ended up losing out because it's a Netflix movie - the Academy may not have wanted to set the precedent of a streaming service winning the top prize in film.

Plus, Roma's director Alfonso Cuaron has already been generously rewarded tonight already, not least with one of the night's top awards - best director.

We're still backstage at the Dolby theatre and hoping to hear from tonight's big winners - Rami Malek, Olivia Colman, Spike Lee, Mahershala Ali and the team behind Green Book very soon.

Stick with us as we bring you all the backstage interviews from the likes of Olivia Colman and Rami Malek. We'll also be bringing you social media reaction plus all the pics from the post-Oscars parties. The night is still young!

“It's genuinely quite stressful. *Tears*. This is hilarious, I’ve got an Oscar. I have to thank lots of people and if I forget anybody I’ll find you later and give you a massive snog.

"Yorgos, my best director and my best film and Emma and Rachel, the two best women in the world to fall in love with - you can imagine it wasn't a hardship. To be in this category, and these extraordinary women and Glenn Close, you are my idol and this is not how I wanted it to be. I love you all. Lindy King, my agent who took me on 20 years ago - thank you so much. My mum and my dad and my kids who are at home and watching, well, if you're not then well done, but I sort of hope you are. This is not going to happen again.

"Any little girl who's practising their speech on the telly - you never know! I used to work as a cleaner. I used to love that job. Oh - ‘please wrap up’ *blows raspberry*. Ed [husband] you're my best friend and best supporter and he's going to cry. I’m not. Thank you so much. Fox, everybody, the cast the crew. Thank you, argh, thank you so much Lady Gaga!"

Here he is writing his acceptance speech backstage!

Roma's Alfonso Cuaron - it's his third win tonight after cinematography and foreign language film. Will he have anything to say this time?!

He does, thanking the film's lead actors, cast, crew, family and Mexico.

Lots of muchas gracias basically.
