Cameron Diaz Poses in Switzerland as the New Tag Heuer Muse

Cameron Diaz wore a LBD and a big Tag Heuer watch to an event in Switzerland last night. She hit the red carpet during a Tag Heuer event during the Baselworld watch and jewelry fair in the city of Basel. Cameron is one of the brand's celebrity ambassadors, having announced a deal with Tag Heuer last year during June. She's also the muse for their new Link Lady collection. In a press release, Cameron spoke about the link lady timepiece, saying she's "equally comfortable wearing it on the red carpet or in my day-to-day life." Cameron rocks a different accessory - a baby bump - in the new What to Expect When You're Expecting trailer. Her character, a mother-to-be, is seen rushing into the delivery room with her husband, who's played by Matthew Morrison.
