Teen abstinence spokeswoman Bristol Palin announced on 25 June that she was expecting her second child out of wedlock. Palin, the 24-year-old daughter of conservative politician Sarah Palin, made the unexpected announcement on her blog.

"I wanted you guys to be the first to know that I am pregnant," Palin wrote. "Honestly, I've been trying my hardest to keep my chin up on this one."

The former reality TV star, whose first child Tripp was born in 2008, said she knows "at the end of the day there's nothing I can't do with God by my side". She added, "I know this has been, and will be a huge disappointment to my family, to my close friends, and to many of you."

The announcement comes just a month after Palin broke off her wedding to US Marine veteran Dakota Meyer. The soon-to-be mother of two was previously engaged to the father of her son, Levi Johnston, but the engagement was later broken off.

According to the NY Daily News, Palin has worked to spread a message of abstinence in her work for the National Campaign to Prevent Teen and Unplanned Pregnancy. Reports stated she earned $262,500 for her work as a teen pregnancy prevention spokesperson for Candie's Foundation.

Palin asked in her blog post that her and her son's privacy be respected in light of her new pregnancy. She added "I do not want any lectures and I do not want any sympathy." The baby's father's name was not mentioned in Palin's statement.

While former Republican vice president nominee did not comment on her daughter's second pregnancy, the news caused many to give their opinions on social media.

"Does Bristol Palin not know about birth control? When you have money/access, it's REALLY easy to not get pregnant. Very easy," tweeted @mstharrington.

Meanwhile other defended Palin from "slut-shaming" attacks.
