Track Palin divorce: Sarah Palin's son and Britta Hanson end their marriage

Track Palin is ending his marriage to his wife of a year and a half, Britta Hanson. The eldest son of Sarah Palin and his soon-to-be ex-wife are the parents of toddler Kyla Grace.

TMZ reports that Palin, 23, and Hanson, 22, were former high school sweethearts. The couple announced that Hanson was giving birth to their daughter not long after they tied the knot. Palin and Hansen married in May 2011, and gave birth in August.

The now-split couple has jointly signed divorce documents in an Alaskan court. By Alaska law, that move means they have already fully settled their property and custody issues, including child support. TMZ claims Palin and Hanson had to watch a 48-minute video about how their divorce will impact their 1-year-old child.
