Kristen Bell and her fiancé Dax Shepard both matched in sparkly attire at the CMT Music Awards in Nashville today. The petite actress had co-hosting duties with country musician Toby Keith for the awards show, which is voted for by fans and recognises country music videos and television appearances. It was also attended by Carrie Underwood, Ashley Greene, Hayden Panettiere and some of the biggest names in country music. Carrie, in a short sequinned dress, was accompanied by her husband Mike Fisher, while Ashley and Hayden posed solo. Last year’s big winner for video of the year, Taylor Swift, wasn’t there, but she’s still in the headlines since John Mayer has made some comments about her song “Dear John,” which was written about him after their relationship ended in early 2010.
