Soon to be Mrs. Sean Lowe is super cute Catherine Guidici showing off her hot bikini body in a yellow bikini at the beach. Looks like constant workouts in preparation for her January 26 wedding to Bachelor star Sean Lowe have paid off. On Saturday Catherine Giudici looked sizzling in a neon yellow bikini as she sunbathed with friends in Miami. The day out was part of a weekend long bachelorette celebration with over a dozen girlfriends. On Sunday the 27-year-old tweeted, ‘Life is fun. I am lucky to have the coolest chicks to call my friends!’ Where was my invitation? Guys can go to girl’s bachelorette parties these days…I would have stripped.
