Kris Humphries -- Partying Shirtless in Miami

Kris Humphries Partying Shirtless in Miami

Now that his ex-girlfriend Myla Sinanaj says she's 100% not pregnant with his spawn, Kris Humphries celebrated by partying shirtless in South Beach this weekend.

With no more baby mama to worry about, the 27-year-old flashed his Calvins while throwing back cocktails with pals.

Miami is brutally hot in the summer, hopefully Kris used protection this time.
