The singer - who announced her pregnancy in November 2010 - posted an emotional message on her website on Friday in which she shared her hopes for the baby.
"I have a life inside of me, and I want her or him to know that I will accept him or her with open and loving and welcoming arms," she wrote.
"And though I will prepare this little munchkin for a sometimes cruel world, I will also equip this kid to see all the beauty in it as well."
She added: "There are those that accept us with all of our flaws. I do that with my fans/friends, and I will do that with my child, whoever they decide to be."
