4. Tina Fey

Tina Fey is anything but shy when discussing her sex life. The comedian has consistently cracked jokes about how long it took her to lose her V-card. Fey told David Letterman that she waited until she was 24 to finally seal the deal with Jeff Richmond, who she incidentally wound up marrying. Joking with Letterman, Fey attributed her chastity to “just good, Christian values… or bein’ homely.”
