"I am thrilled to be on this show and to be part of a program that educates teens and young adults about the consequences of teen pregnancy," Palin said in a statement.
Bristol Palin, daughter of former vice presidential candidate Sarah Palin, will play herself as a friend to the show's protagonist, Amy, at a music program for teen mothers. "Secret Life" focuses heavily on how Amy's family and friends deal with her own unexpected pregnancy.
"We're thrilled to have [Bristol] join us, and I think she will bring additional attention to the issues facing teen parents that we've been exploring for a couple seasons now," "Secret Life" executive producer Brenda Hampton said in a statement.
Bristol Palin, who became pregnant in high school, was thrust on the national stage with young baby in arms when her mother Sarah Palin was named John McCain's running mate in the 2008 presidential election.
Bristol was briefly engaged to the baby's father, Levi Johnston, whom she has recently has taken to court to get full custody of their son, Tripp, and to ask for increased child support.
Last month Bristol appeared on "The Oprah Show" to defend her pledge to abstain from sex again until she gets married.
Last spring, Bristol told "Good Morning America" she wanted to use her fame to spread her abstinence message.
"Regardless of what I did personally, I just think that abstinence is the only ... 100 percent foolproof way to prevent pregnancy," she told "Good Morning America" then. "It's a hard choice, but it's the safest choice and it's the best choice."
