Bristol Palin is pregnant and this is news.

The 24-year-old daughter of former vice presidential candidate and “SNL” punching bag Sarah Palin has spent the last seven years since her mom’s failed bid for the White House making abstinence (and holiness in general) her personal and very profitable cause celeb.

In 2008, 17-year-old Palin’s unplanned teen pregnancy threatened to derail her mom’s White House hopes. But her potentially embarrassing narrative quickly turned to one of resilience and the reality shows followed. Palin appeared on season 11 of “Dancing with the Stars” and in her own Lifetime docu-series, “Bristol Palin: Life’s a Tripp.”

In 2009, Palin earned $262,500 as The Candie Foundation’s teen pregnancy ambassador but that same year told Fox’s Greta Van Susteren, “everyone should be abstinent or whatever but it’s not realistic at all.”

Palin, whose recent engagement to former Marine and Medal of Honor awardee Dakota Meyer ended mysteriously and abruptly, broke the baby news on her personal blog Thursday.

“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,” wrote Palin.

“I know this has been, and will be, a huge disappointment to my family, to my close friends, and to many of you,” continued Palin, mother of 6-year-old Tripp with her first ex-fiance Levi Johnston. “But please respect Tripp’s and my privacy during this time. I do not want any lectures and I do not want any sympathy.”

Thus far, Meyer, who has more than 65,000 followers on Twitter and who Mama Palin once called “an American Hero,” has remained silent on the subject of Bristol’s baby.
