Jason Momoa says Aquaman will be back, Emilia Clarke talks about meeting Beyoncé, Regina King reveals she feared she would always be cast as a wife, Ross Noble jokes about his Olivier nomination and Camila Cabello performs live in the studio.

Regina King, talking about winning an Oscar for If Beale Street Could Talk, says: "They gave me a little talk about what to do, but all of it is such a blur in so many ways. It still feels surreal, but I felt so much love in that room. Once you've won the pressure is off, and they do have a bar!"

Asked about her action character in the new TV series Watchmen, she says, "I'm a complete bad-ass." Talking about doing stunts she says, "I'll do some of them, but I have a stunt double to do all the hard stuff because I am not landing on the ground! I don't have to do that. I'm 48 and I don't have anything to prove! I do sometimes wish that the double could come in to do some of the sex scenes - that would be awesome."

Talking about being typecast as a wife in movies for a while after Jerry Maguire, she says: "When you get a call asking you to play Samuel L Jackson's wife you think, 'Surely you meant daughter or mistress?' I love Sam, but that told me it was time to shift."

Emilia Clarke, talking about the Oscars and meeting Jay-Z and Beyoncé, says: "I did not expect to see them in the flesh. I wasn't expecting that at all, I was just amazed to be invited. I was like, 'How did that happen?' When I met Queen Bey I was too many drinks in and started crying. It didn't go well. I think she got out of there very quickly!"

Asked about her friends and their apparent lack of interest in her career, she says, "It started with things like, 'We can't afford to stream Game of Thrones, we don't have the money, sorry Emelia,' then it was, 'We'll try and download it,' then it was season eight and I was having a screening of the last episode and they said, 'So we've seven and three quarter seasons to catch up before this Sunday!'"

Talking about her new film, Last Christmas, Emelia says: "Filming at Christmas in London last year was bonkers. Because we were in Covent Garden and Regent Street, we started at midnight and finished at midday and I was in a perpetual sort of hangover state. Starting filming at midnight in the centre of London had its issues - there are a lot of drunk people wandering around and shouting at us and leaning out of windows telling us how bad we were!"

Ross Noble, talking about his nomination for an Olivier Award for his performance in Young Frankenstein the West End, says, "It was cool, but on the night, I couldn't go because I was back on tour. If you can't attend they show a picture of the nominee and I wanted them to use a photo of me on the sofa in my pants eating a packet of crisps. But apparently, it's not the 'done thing'!"

Asked about his new tour Humournoid, he says: "It's very fashionable these days for stand-up tours to have a theme but I don't have one. It's just me talking absolute rubbish for two hours."

Jason Momoa joins Graham for a chat. Asked about his new TV series See, Jason says: "We had extensive 'blind' training and had to use our other senses. It is a lot more honest and really beautiful. When we took off the eye masks everything seemed diluted."

Talking about the scope and scale of the epic series, he says, "Apple invested big on this one and it shows. We went to the most far out places in British Columbia because they didn't want to shoot anywhere that has been shot before and they went to huge lengths to make it."

Asked about the success of Aquaman and the possibility of a sequel, he says, "We will be back - probably in a year from now. I was very excited about the reaction. We have a script, which we've pitched and I' m very passionate about it."

Camila Cabello performs Liar live in the studio, before joining Graham for a chat about her new album. Greeting Emelia with, "My queen!" and giving her a tiny dragon, Camila reveals, "I am the biggest Game of Thrones fan in the entire world. I am just freaking out to meet you guys. I literally went through all eight seasons in a month this year."
