Bristol Palin Reveals She Is Pregnant Again: I Know This Will Be a 'Huge Disappointment'

Bristol Palin said it herself… she has "big news."

Sarah Palin's 24-year-old daughter revealed on Thursday that she is pregnant with her second child, and it sounds like it wasn't planned.

"(I'm announcing this news a lot sooner than I ever expected due to the constant trolls who have nothing better to talk about!!!)," she began her post. "I wanted you guys to be the first to know that I am pregnant."

Palin, who called off her wedding to Dakota Meyer last month, is already mother to 6-year-old son Tripp, whom she had with ex-fiancé Levi Johnston.

"Honestly, I’ve been trying my hardest to keep my chin up on this one. At the end of the day there’s nothing I can’t do with God by my side, and I know I am fully capable of handling anything that is put in front of me with dignity and grace," Bristol wrote on the religious site Patheos. "Life moves on no matter what.  So no matter how you feel, you get up, get dressed, show up, and never give up. When life gets tough, there is no other option but to get tougher."

Interestingly, Bristol does not reveal who the father of her unborn child is.

She continued, "I know this has been, and will be, a huge disappointment to my family, to my close friends, and to many of you. But please respect Tripp's and my privacy during this time. I do not want any lectures and I do not want any sympathy. My little family always has, and always will come first. Tripp, this new baby, and I will all be fine, because God is merciful."

Palin announced she was engaged to Sgt. Meyer in March, but they split two months later. "I know God’s plan is greater than anything else, and Tripp and I are in Alaska beginning to rebuild our lives under much different circumstances than we anticipated," she shared at the time.

Sarah Palin has yet to comment on her daughter's news.
