Princess Mary Goes Yachting, No Baby Bump Yet (PHOTOS)

Denmark's Princess Mary was spotted aboard the Royal Yacht Dannebrog as the Danish Navy celebrated its 500-year jubilee in Copenhagen Harbour on Tuesday, looking svelte in a white frock...and certainly not showing any signs of pregnancy, much less being pregnant with twins! Check out images below of Danish Queen Margrethe, Prince Consort Henrik, Mary's husband Crown Prince Frederik, and their children Prince Christian and Princess Isabella.
