It was the premiere of the new Pirates of the Caribbean film and Ricky, being Newsround's Red Carpet King, got in on the action.
It's not all glamour and gossip though - Ricky had to wait for aaaages before the stars appeared!
The new film is called On Stranger Tides.
And as usual its main character is Hollywood mega-star Johnny Depp.
Ricky managed to grab a word with Geoffrey Rush who said he'd make Johnny Depp walk the plank so HE could be the main part!
Robbie Kay is one lucky teenager. The 15-year-old plays the cabin boy in the film.
Penelope Cruz stars alongside Depp in the film.
Loads of celebs turned up to see it, including one of our favourites - Chipmunk.
Three of the McFly boys were looking very cool with their shades on their T shirts.
