While mommy-to-be Jessica Simpson decided to pose nude on the cover of Elle magazine, fellow pregnant star Hilary Duff is finding ways to bare all about her pregnancy in a completely different (and hilarious) way.

The actress stars in a new Funny or Die video about some of the unglamorous side effects of pregnancy -- including lots and lots of unwanted hair.

The 24-year-old star laments, "After I got pregnant, my hormones caused so much hair growth that I felt like a yeti...or Robin Williams." And she wasn't kidding: back hair, facial hair, even knuckle hair -- nothing is left unmanned.

But thanks to a product called NoGrowActiv, all her hair problems have finally been solved. And the side effects aren't that bad...well, that is if you don't mind giving birth to a hair baby.

Watch the clip below, and enjoy the giggles!
