Britney Spears played bridesmaid in her assistant Brett Miller's wedding in Miami on Saturday. We saw her heading out of town with Jason on Thursday before reappearing all dressed up for their good friend's big night. They danced and looked "cute and romantic" before leaving the wedding and continuing their night at the Fontainebleau club LIV. Last week, it was announced that Britney's new album will be released on March 15 while her single, Hold It Against Me continues to break records and we wait patiently for her latest sexy music video to premiere any day. If you are eagerly awaiting the new release, you can start supporting Brit at her limited time pop-up shop on Feb 1 where 36 random shirts will be signed by Brit.
