Kellie Pickler Sports Bikini in the Jungle

While most of us were hard at work and looking forward to the weekend on Thursday, Kellie Pickler was in the rain forest ... in a bikini. "Island sun & rum...nothing but fun!" the 'Tough' hitmaker tweeted a few days ago, as she soaked up a little bit of warm weather on her post-Christmas vacation. Pickler rubbed it in when she posted a photo of herself wrapped in a towel in front of a waterfall, but she'd better hurry home -- 2012 is almost here, which means her new '100 Proof' album will be here soon, too!
