The social-media throwdown began last week when makeup-free paparazzi pics of the "Fancy" emcee surfaced online and Snoop promptly compared her fair skin and blond hair to that of an albino woman with cornrows.
Snoop, 42, real name Calvin Broadus, continued picking on her with a slew of escalating mean-spirited memes and posts making less-than-flattering comparisons.
Iggy, 24, real name Amethyst Amelia Kelly, responded to the bullying with since-deleted tweets that were captured by E! News.
"@snoopdogg why would you post such a mean pic on insta when you send your body guards to ask me for pictures every time we are at shows together?" she wrote. "My bodyguard stopped the fire truck that saved your friends life in canada when he almost burnt down the hotel ... And everytime I've spoken to you, you've always been nice as hell, I'm disappointed you'd be such an ass for no reason."
