The world should bow down and kiss Diddy's feet -- because if it weren't for his new coffee table book about female backsides ... we'd never see this picture of Lady Gaga's perfectly-shaped ass.

Unlike Irina Shayk's inkblot-covered backside -- also featured in the butt book by Diddy and Interscope chairman Jimmy Iovine ... entitled "CULO" -- Gaga happily bared all in her most shocking outfit yet ... nothing.

She was born this way.
