Tax documents show unwed mother Bristol Palin earned more than $262,000 for her role in helping raise awareness for teen pregnancy prevention in 2009.
Bristol Palin was 18 when she was appointed as a teen ambassador for the New York-based foundation in 2009, months after giving birth to son, Tripp. She and the 2-year-old boy's father, Levi Johnston, are no longer together.
Palin, who still works for the foundation, told The Associated Press last year that girls would think twice about having sex if they knew how tough it is to be a mother. She said she "wasn't prepared at all" for the dramatic changes in her life since becoming a mom.
"I don't think anyone realizes how difficult it really is until you actually have a screaming baby in your arms and you're up all night," Palin said.
When she was first named to the ambassador role, Palin said in a statement she felt she could be a living example of the consequences of teen pregnancy.
"If I can prevent even one girl from getting pregnant, I will feel a sense of accomplishment," she said at the time.
