Nick Cannon Scoffs at Vasectomy Question, 'My Body, My Choice!'

Nick Cannon has words for anyone who thinks he's had too many kids ... "My body, My choice!"

Nick appeared on CNN's NYE show and the ever-inquisitive Andy Cohen asked him if he'd consider getting a vasectomy. Nick's response was essentially ... not anyone's biz but mine.

Andy pressed the father of 12 ... "Do you want to hit 20?"

Nick was honest, even if the answer wasn't especially satisfying ... "Clearly, I don't have a plan. That should've been clear from the jump."

As we reported, Nick welcomed baby #12 last month. Another great name -- Halo, the little girl he had with Alyssa Scott.

A month before that, Nick welcomed another baby girl, Beautiful Zeppelin with Abby De La Rosa. And in September, he welcomed son Rise Messiah with Brittany Bell.

Two weeks before Rise was born, Nick welcomed daughter Onyx Ice with LaNisha Cole, a 'Price is Right' model.

And in June, he and Bre Tiesi welcomed their first child together, Legendary.
