Don’t make poor Emily Maynard sleep naked alone!

The gorgeous Season 8 Bachelorette just tweeted a last call for anyone wanting to join her in a good cause. “Last day to #SleepNaked w/ #TeamEmily!” Em tweeted on September 17. “Pledge now & help me win 4 my fave charity @TheMochaClub! http://bit.ly/17oCdh9  #swisspers #ad.”

What the heck is going on? Em is repping Team Blonde for the Swisspers “Sleep Naked Face-Off.” The Swisspers website invites fans to take the pledge to sleep naked — as in, without their makeup — for their team. The celeb with the most pledges will throw the ultimate sleep naked party on National Sleep Naked Night, which is September 19 at 9 p.m. She will also answer fan questions, live on video.

Right now, Emily's Team Blonde is losing to reality star Danielle Jonas' Team Brunette. (Those dang Jonas Brothers fans!)

According to the site, Emily's charity, The Mocha Club, "is a community-based organization that makes a difference in various African communities. Members start by giving $9 a month — the cost of a few mochas — to one of Mocha Club's ongoing projects in Africa." Africa has a special place in Emily's heart. You may remember she and her Bachelorette ex Jef Holm went to Ghana in August 2012 to build wells with Jef's company People Water. Later, she went to Ethiopia with BlogABLE to fight poverty and help women in Africa start small businesses.

Head here to pledge Team Blonde, which is also Team Emily. You may not actually get to see her naked in real life, but you can settle for helping to make the world a better place.
