Aly Michalka Bikinis, Ariana Grande Leggy Perfection, Arianny Celeste Cleavetastic Highlight the Sextastic Twitpic Roundup

With December fully upon us and Winter breathing its chill air down our necks (admittedly, I don't know how to describe Winter, I live in L.A.), there's no slowing down the sextastic self-promoting celebrities from traveling out to the world's warm weather spots for the purpose of showing off their hot bodies and tightly worked bottomsides. Really, if airline travel had been invented for solely this purpose, that would've been reason enough. On to the candids.

This week's Sextastic Twitpic Roundup includes the glorious legs of cheeky Ariana Grande, Ashley Sky with more bikini body perfection, Nina Agdal hand-bra covered goodness, Arianny Celeste with just one ridiculous beach body, Aly Michalka showing off her naturally fine female form, Paris Hilton bikini primping, Erica Mena serious boobtastic show, and much much more. You owe it to every single lady who got punched by another lady on Black Friday to check out each and every one of these wicked hot selfies and socially shared celebrity candids. Enjoy.
