Abstinence advocate Bristol Palin pregnant for the second time

Bristol Palin says she's pregnant for a second time.

The daughter of 2008 Republican vice presidential nominee Sarah Palin announced the pregnancy on her blog Thursday. Her representative, David Martin, and Palin family lawyer John Tiemessen confirmed the blog post.

The 24-year-old wrote that she knows this is a "huge disappointment" for her family, close friends and fans. She's asking people to respect her privacy, and that of her son Tripp, saying, "I do not want any lectures, and I do not want any sympathy."

"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.

"Life moves on no matter what. So no matter how you feel, you get up, get dressed, show up, and never give up," she wrote.

She was engaged to Medal of Honor recipient Dakota Meyer, but the wedding was called off days before the ceremony last month.

Palin was 18 when her mother was selected by US Sen. John McCain to be his running mate in the 2008 presidential election. Shortly after the selection, it was announced that Bristol was pregnant.

Sarah Palin said Bristol and the baby's father, later revealed to be Levi Johnston, would marry, but the couple eventually ended the relationship.

Bristol Palin later became a paid spokeswoman advocating abstinence and warning against teenage pregnancies. She twice performed on Dancing with the Stars and had a short-lived cable television show, Life's a Tripp.
