Bristol Palin is apologizing for herself and her younger sister for their Facebook rant against posters criticizing their family. Palin posted the apology on her Facebook page, saying she and her 16-year-old sister Willow "shouldn't have reacted to negative comments about our family. We apologize."

Willow Palin used a homophobic slur against a poster on her Facebook page who criticized her mother's new documentary series "Sarah Palin's Alaska." Then, she and Bristol engaged in a stream of offensive comments with posters who continued to slam the family.

Bristol ends her apologetic post by thanking those who are supporting "the great competition in Dancing with the Stars!" She is among three teams who made the finals this week.
