Hollywood actress Jennifer Lawrence has said she felt like "a radio contest winner" when she met Ariana Grande.

Singer Grande, 28, features in the film Don't Look Up as part of a music "power couple" in which she plays pop star Riley Bina alongside rapper Kid Cudi (real name Scott Mescudi), who stars as DJ Chello.

Speaking at a press conference for the film, Lawrence said: "I mean, I’m a huge fan of her music and Scott’s…"

The Oscar-winning actress, 31, who is expecting her first child with New York City art dealer husband Cooke Maroney, added: "It’s just like, you know, like overwhelming. 'Cause our worlds don’t normally collide.

"I just felt like a radio contest winner. I just didn’t know how to talk to her. So I just, you know, did my best."

In the film, Grammy winner Grande and Kid Cudi perform the song Just Look Up which they co-wrote and has been released as a single.

Singer Cudi, who has worked with Jay-Z, Eminem, Kendrick Lamar and more, described Grande as "an incredible artist" adding: "And you know, her vocal performance is just like stellar… it’s like her voice is just amazing."

The film marks DiCaprio’s first screen appearance since Quentin Tarantino’s Once Upon A Time In… Hollywood in 2019, while Lawrence has not starred in a movie since the X-Men instalment Dark Phoenix, also in 2019.

The star-studded cast also includes Meryl Streep, Timothee Chalamet, Cate Blanchett, Tyler Perry, Sir Mark Rylance, Ron Perlman, Himesh Patel and Melanie Lynskey.
