Shrek is back!

It's time to go green again as Shrek's back, as are the A listers who provide the voices behind the successful comedy cartoon characters.

Shrek regulars were out in force for the London premiere of the third movie in the series. The stars gracing the green carpet included Mike Myers, Antonio Banderas and Cameron Diaz.

But it was Justin Timberlake who got the biggest cheer of the night, as the sexy back singer joins team green monster for the first time.

He said: "Well I play King Arthur, but not exactly as we know him from the myth. He's Arti and he's a high school student and he's just not that cool. That's how I'll describe him."

All the cast including British actors Rupert Everett and Ian McShane were on great form. It wasn't even a problem for ex's Cameron and Justin to spend time together.

There's a whole lot more Shrek planned with a musical and TV show on the way, but first of all the latest monster hit is out at the end of June.
