Kristen Bell and Dax Shepard are engaged. The 'When in Rome' couple - who have been dating for around two years - are set to tie the knot after Dax proposed over the festive period. A representative of Kristen Bell confirmed the very good news. "They got engaged over the holidays," the rep said.

Kristen Bell - who presented an award at the 52nd Grammy Awards in Los Angeles, California last night - showed-off her very fresh engagement ring (sorry, we have no photo) while presenting. Check out Kristen Bell at the World Premiere of Touchstone Pictures 'When In Rome' at the El Capitan Theatre in Hollywood, California on January 27, 2010.
