Believe it or not, but Robert Pattinson wanted to become a rapper in his teenage years.

The British actor would have even called himself Big Tub!

The revelation came when Pattinson appeared on 'Late Night with Seth Meyers' on Tuesday (June 17th) to promote his new flick 'The Rover.'

The 28 year-old actor asserted that this was "100 percent," true and confirmed to Meyers, "I still kind of do. I was Big Tub, that was my rap name."

While the host, as well as the studio, couldn't help but laugh at the silly moniker, Pattinson said, "I was very paranoid about my weight."

But, even today he still seems conscious about stepping on the scales, "I got quite sick in the last couple of days and I'm so excited about it. Next week I'm going to be so skinny!" he added.

This wasn't just an idea in his head, Pattinson actually attempted to record a few songs until realizing he didn't know how to.

"I didn't know how to scratch, so I used to pull up and down the zip on my hoodie and record it," the Hollywood hunk confessed, without cracking a smile. "It sounds exactly like it! [We were] Big Tub and the Tabby Cats."

This isn't the first time the 'Water For Elephants' actor has admitted this either, when appearing on 'The Oprah Winfrey Show' back in 2010, R-Patz confessed, "I used to want to be a rapper when I was, like, 14."

Pattinson also told Meyers about his experience trying to make friends when first moving to Los Angeles.
