Lady GaGa and Justin Biber will become aliens

Lady GaGa and Justin Biber are set to make an appearance in upcoming Men In Black 3 movie. Both singers – alongside with Tim Burton – will have a short cameo portraying aliens.

Talking about their involvement in filming, Men In Black 3 director Barry Sonnenfeld said: "The challenge is getting celebrities that are famous, will give you permission and won't be like: "Who's that guy?" in 10 years. In this film there are a few people that you'll see up on the surveillance board including Lady GaGa, Tim Burton, who probably knows more about aliens then I do, and let's see who else… Justin Bieber".

Previous Men In Black movie also featured a number of celebrities, including Michael Jackson who played Agent M.
