Levi Johnston and Bristol Palin Will 'Discuss' Move to Arizona, Plans for Son TrippBristol Palin is set to relocate to a new home in Arizona, but Levi Johnston, father of Bristol's 2-year-old son Tripp, needs to approve first.

Johnston's rep told TMZ Levi is "aware" of Bristol's plans to move away from Alaska, but that the two have yet to talk about relocating Tripp.

"According to court officials in Alaska, in order for a parent with primary custody -- like Bristol -- to relocate a child, she would need either consent from the other parent or she could file a motion for approval from a judge," TMZ reports.
