Kendall Jenner, Ashley Benson, Irina Shayk, Paulina Gretzky All in Bikinis for the Sextastic Twitpic Roundup

Summer is officially here. No, not according to the dates on my nineteen different sizzling hot and politically incorrect wall calendars, but according to the slew of bikini photos the self-publishing set of celebrities are kicking out now. It's tremendous and we couldn't be happier for them, their egos, and our eyeballs.

This week's Sextastic Twitpic Roundup includes Kendall Jenner showing off her bikini bottom from Greece, Ashley Benson sweet bikini shot, Irina Shayk with an incomparable bikini bottom, Jo Jo Levesque stretching her legs, Paulina Gretzky flashing bikini bottom, Vanessa Hudgens and Stella Hudgens showing off, and much much more. You owe it to the May flowers to shower some attention on each and every one of these hot selfies. Enjoy.
