Heidi Klum Subathing Topless, Sara Jean Underwood Motorboating, and Emma Roberts Panties Highlight the Sextastic Twitpic Roundup

The holiday season hardly puts a a damper on the 365-days a year effort of our favorite celebrity hotties from self publishing skin-filled pictures of themselves to keep their fans chomping at the bit for more. Sort of all-year round not so secret sextastic Santa Claus series of givings, with images of their own hot-selves as the presents. It's fairly genius.

This week's Sextastic Twitpic Roundup includes a few hot shots of super hottie Candice Swanepoel, Candace Bailey motorboating Sara Jean Underwood, Amanda Bynes cleavage, Heidi Klum sunbathing sans top, Ashley Tisdale dancing, and much much more. You owe it to St. Nick, the patron saint of toy trains (and never received GI Joe action figures for me) to check out each and every one of these celebrity self-published pics. Enjoy.
