Abstinence campaigner Bristol Palin is pregnant

We **think** Bristol Palin may have fallen off the wagon with the whole abstinence thing.

The daughter of high-profile US politician Sarah Palin, has announced on her blog that she is expecting her second child.

Bristol launched a high profile abstinence campaign after falling pregnant with her first child when she was 18- just one month after her mum Sarah was selected as John McCain’s running mate in the 2008 presidential election.

And to say the 24-year-old is less than thrilled with the news of her current pregnancy is a bit of an understatement.

In her blog she wrote: ‘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.

‘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.

‘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.’

Eek.

And to make things worse for Republican America she called off her wedding to Medal of Honour winner Dakota Meyer a month a go.

Bristol announced her first pregnancy shortly after her mum Sarah was chosen as John McCain’s running mate in the 2008.

Sarah said Bristol and the baby’s father, later revealed to be Levi Johnston, would marry, but the couple eventually broke up.

Bristol later became a paid spokeswoman advocating abstinence and waing against teenage pregnancies.

She twice performed on Dancing With The Stars and had a short-lived cable television show called Life’s A Tripp.
