Paul Mescal traded the set of Sam Mendes' four-part Beatles saga for a mosh pit Saturday, turning up at London's All Points East festival to support his younger sister, singer-songwriter Nell Mescal, as she played her own set on the bill.

Fans caught the Gladiator II star filming videos and singing along from the crowd before the siblings wandered the festival grounds together afterward. Paul also linked up with his Beatles co-star Harris Dickinson, with the pair spotted hugging while watching another act together.

Nell, 23, has been building her own indie-folk following since her 2020 debut single "Crash," and clips of her big brother cheering from the barricade quickly made the rounds online.
