US singer and actress Selena Gomez joined her co-stars on the red carpet at the London Film Festival on Friday, for the UK premiere of her Oscar-tipped film Emilia Pérez.

The Spanish-language musical was one of the breakout hits of the Cannes Film Festival earlier this year, where Gomez and three of her co-stars were jointly named best actress.

The others - Zoe Saldaña, Adriana Paz, Karla Sofía Gascón - appeared alongside Gomez in London, where the film hopes to continue its momentum in the awards race.

Emilia Pérez follows a Mexican Cartel leader (played by Gascón), who asks a high-powered lawyer named Rita (Saldaña) to help him fake his own death.

But the reason he wants to retire and disappear from the world of crime isn't what you might expect - the cartel leader wants to change gender and live a new life as a woman.

The rest of the film focuses on four women, including the newly transitioned Emilia Pérez, as they each pursue their own version of happiness in modern-day Mexico.

Pérez is portrayed by Spanish trans actress Gascón, who has been tipped as a possible best actress contender in the forthcoming awards race.

Gomez plays the drug lord's wife, who is kept in the dark about her former lover's new identity, while Paz portrays Emilia's new romantic interest after transitioning.

All four of the film's stars walked the red carpet ahead of the film's UK premiere at the Royal Festival Hall as part of the London Film Festival on Friday.
