Hollywood superstar Gerard Butler thrilled fans as he posed with rap legend 50 Cent for new movie Den Of Thieves.

The Paisley-born actor grabbed a quick selfie break with Curtis '50 Cent' Jackson as they both enjoyed bootcamp for the up and coming film.

He entitled the picture: "#DenOfThieves boot camp with the man 50 Cent".

The unlikely duo star in the thriller slated for 2018. Based on Pulitzer prize-winning book by writer James B. Stewart, it follows the lives of a gang who plan a bank heist in Los Angeles. 

The rapper will play one of the bank robbers in the film, co-produced by Butler.

Filming is expected to start in Atlanta in the United States this month.
