Cameron Diaz and Mike Myers posed for pictures at the premiere of Shrek The Third in Los Angeles in America on Sunday.
Cameron does the voice of Princess Fiona in the animated film, which is out in the UK this summer.
And Mike is the voice of the friendly green ogre Shrek! Shrek 2, released in 2004, took the most money ever for an animated film and producers have high hopes for the third film.
Here's Eddie Murphy - he voices the very talkative Donkey. It was really sunny and loads of guests were wearing sunglasses at the big event.
Mike plays up to the cameras with Antonia Banderas, who plays Puss in Boots in the fairytale animation.
Singer Justin Timberlake also stars in the film. He does the voice of Artie, a teenage King Arthur who has no interest in his claim to the throne.
Justin and Cameron used to go out together but broke up last year. But when they met on the green carpet they gave each other a friendly kiss and a hug.
