Rap mogul and fashion designer Sean Combs is dropping the "P" from his moniker "P. Diddy."

Combs says he now wanted to be known just as "Diddy" because his old name was causing confusion and he wants to "simplify things".

The 35-year-old singer and producer has already changed his nickname once - from Puff Daddy to P Diddy in 2001.

Diddy tsays his name was starting to confuse everyone, including himself.

Combs says, "Nobody knew what to call me. I'd notice that people were uncomfortable when I'd meet them for the first time, and then they'd ask me what they should call me."

Combs leaves no room for confusion with the new streamlined version of the well known name. "One word. Five letters. Period."
