It could be "Game on!" for Bristol Palin and Levi Johnston.
UsMagazine.com reports Levi and Sarah Palin's daughter -- who have been on icy terms since calling off their engagement in March 2009 -- could once again be a couple.
According to their source, "Now that Mama Palin is out of the picture and Bristol is on her own in Anchorage, they spend more time together than most people think."
The source adds, "Levi even stays overnight. I even think they are back together."
