Will Smith, Tommy Lee Jones and Frank the Pug, make room for Justin Bieber and Lady Gaga.

Men in Black III director Barry Sonnenfeld recently confirmed that both pop stars will have small roles in the upcoming summer blockbuster.

In an interview with Collider, Sonnenfeld revealed that Bieber and Gaga would play aliens alongside director Tim Burton.

"In this [installment] 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 than I do, and let's see who else... Justin Bieber," 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."
