Seeing Daniel Radcliffe, Rupert Grint, Emma Watson and JK Rowling together and all dressed up can only mean one thing - it's time for a Harry Potter premiere!
The Harry Potter stars were out in force on Thursday night for the world premiere of Harry Potter and the Deathly Hallows Part 1, in London.
Fans camped out for hours to see their favourite stars. Emma Watson was one of the first to arrive and wowed the crowds in her black lace and feather mini-dress.
Rupert Grint said he thought the new film would shock fans: "A lot of characters die and it's quite scary," he said. "The whole world [of Harry Potter] is darker."
Ralph Fiennes may be partly responsible for that... He plays the dark Lord Voldemort in the films. And check out his Death Eater buddy at the premiere!
It didn't seem to bother Arsenal striker Theo Walcott and his girlfriend Melanie Slade. They looked pretty happy to be at the star-studded event.
Helena Bonham-Carter is also back as trouble-maker Bellatrix Lestrange. The Deathly Hallows is JK Rowling's final Potter book and has been split into two films.
X Factor hopefuls One Direction were whisked away before we could speak to them, but they still had time to tell us they love Newsround!
Strictly Come Dancing's Tina O'Brien seems pleased to have missed the rain. Despite a few showers, the Deathly Hallows premiere was one of the driest in years!
