MUMBAI: Paparazzi Queen Lady Gaga and Teen-pop star Justin Bieber is all set to make a cameo appearance as an alien in the upcoming trilogy ‘Men in Black 3’.

Director Barry Sonnenfeld revealed that the singers could make an appearance as an alien in the movie, he said, “ In this movie you'll see up on the surveillance board including Lady Gaga, Tim Burton, who probably knows more about aliens than I do, and let's see who else... Justin Bieber... So far we've been pretty luck and people have been kind and interested. I am surprised that Lady Gaga said yes."

Earlier the franchise had jokingly outed some of the famous celeb as an alien which included Steven Spielberg, Danny DeVito, George Lucas, Sylvester Stallone, Isaac Mizrahi, Martha Stewart and Michael Jackson.

Based on Lowell Cunningham's comic, ‘Men in Black 3’ will focus on time travel involving Will Smith (Agent J) and Tommy Lee Jones (Agent K). The final conclusion of the extraterrestrial trilogy is scheduled to release  on 25 May 2012.
