Bristol Palin -- Strolling Through Motherhood

Sarah Palin's 20-year-old unwed daughter Bristol Palin took her adorable two-year-old son with Levi Johnston, Tripp, for a stroll in L.A. on Wednesday.

The teen abstinence spokesperson is getting ready to shoot her new reality show with her former fellow "Dancing with the Stars" contestant Kyle Massey.

One person you probably won't see on her show is Levi's sister Mercede, who just called Bristol "evil" and a "sociopath" in a Playboy interview.
