The 24-year-old single mom took to her blog to share the news, writing: “I wanted you guys to be the first to know that i am pregnant. Honestly, I’ve been trying my hardest to keep my chin up on this one.”

She adds, "I know this has been, and will be, a huge disappointment to my family, to my close friends, and to many of you...I do not want any lectures and I do not want any sympathy."

She says she announced the news sooner than she would have liked because of “The constant trolls who have nothing better to talk about!"

Bristol first made headlines back in 2008 when she got pregnant at the age of 17 during her mother Sarah Palin’s bid for Vice President. She gave birth to a son, Tripp, and got engaged to the boy's father, Levi Johnston, but the two never married and had a nasty breakup.

She has also preached abstinence in the past. In 2009, she vowed to In Touch that she would not have sex again before marriage and said, "I'm not going to have sex until I'm married. I can guarantee it."

No official word on whether the father is Dakota Meyer, who lives in Kentucky.
