American singer D4vd has been arrested and charged with the murder of a 14-year-old girl, Celeste Rivas Hernandez.
Her body was found in his Tesla in Los Angeles in September last year. Prosecutors allege D4vd repeatedly sexually abused the teen before killing and dismembering her, but D4vd denies all the charges.
He has pleaded not guilty to murder, and his attorneys have said they will "vigorously defend” his innocence.
In this episode, we’re joined by Anoushka Mutanda-Dougherty, the host of the BBC podcast Fame under Fire, to explain what we know so far about what happened to Celeste Rivas Hernandez. And we also look at why it took so long for D4vd to be taken into custody.

Harry Styles, Bad Bunny and Shakira are just three of the many huge pop acts that have decided to do residencies — turning away from long world tours and performing night after night in one major city instead. Residencies make it easier for artists to build elaborate shows, help them avoid burnout from constantly being on the move, and save them the effort (and money!) of transporting their crew, costumes and staging. But they can also make it even harder for fans to get the chance to see their favourite artists live.
BBC reporter Mollie Perella explains why residencies are becoming more popular - and why concert tickets are getting more and more expensive. Artists CMAT and Wet Leg tell us what they think about residencies - and whether they would ever do one. And fans share their thoughts on Harry Styles’ upcoming residency in New York.

People frequently turn to AI chatbots like ChatGPT, Gemini and Grok for health advice. Some people argue that using them is similar to an Internet search. But some experts say that chatbots are getting things dangerously wrong.
James Gallagher, the BBC’s Health Correspondent, explains how chatbots work, what the risks are and how the technology is evolving. We also hear from young people about how and when they seek advice from chatbots.

For better for worse, for richer for poorer…but first, can we sign a prenup?
You might have heard about them in relation to celebrity divorce scandals, or even in songs, but recent data suggests prenups aren’t just for the rich and famous anymore. A prenup is a legal arrangement made by a couple before they marry or enter into a civil partnership, which sets out plans for how their wealth will be divided if they divorce. Polls in the US, Canada and the UK show that over half of Gen Z would consider signing one and there’s even a growing number of apps to help you draw up the contract.
So — why are prenups on the rise? And what does it say about modern marriage?
BBC journalist Chelsea Coates breaks down the data behind this - and talks us through the reasons why more of Gen Z are considering signing one. Basma El Atti, a BBC reporter based in Nairobi, explains how marriage differs across the African continent and how conversations around finance before getting married are changing.

For more than three months, Cuba has been struggling under an oil blockade by the United States. It had been getting a lot of its oil from Venezuela, but President Trump put a stop to that.
People in Cuba have been living with all kinds of shortages for decades - food, medicine and of course, oil. This blockade though has made things even more tough and people say they’re exhausted. Santiago Vanegas Maldonado, from the What in the World team, brings us voices of young Cubans who are upset about how their lives have changed and the BBC’s Jose Carlos Cueto Lopez, who is from Havana, takes us through the background to the blockade and what it’s like for people in Cuba.
