Teenage mom Bristol Palin is ruling out having sex again until she gets married. The 19-year-old mother-of-one, daughter of former VP candidate Sarah Palin, says she doesn’t want to make the same mistake again when she got pregnant by then-boyfriend Levi Johnston.

Bristol has been named a Teen Abstinence Ambassador for teen pregnancy prevention organization Candie’s Foundation last year after she gave birth to son Tripp in December 2008.

She told In Touch, “I’m not going to have sex until I’m married. I can guarantee it.”

Her abstinence doesn’t mean she regrets having Tripp, saying, “Tripp is the love of my life – I couldn’t ask for a better baby.”
