As we bid a fond farewell to David Letterman, we're also thinking back on all the sexy and scintillating moments that talk show guests and hosts have brought us over the years. During a 2010 appearance on Letterman, he showed Cher a picture from an appearance she did years ago where he grabbed a look at Cher's be-thonged booty! Who could blame his wandering eyes? Always good for a sexy and scandalous moment, Chelsea Handler appeared fully nude—though her best bits were blurred—on her own show with Ellen DeGeneres in 2014. Craving a little more skin? Why not check out Skinemax siren Kira Reed's panty-less crotch shot from The Howard Stern Show! And don't miss Tina Fey's striptease during her last Letterman appearance in 2015! These talk show tarts will keep us tuning in for more!
