Princess Charlene, a former Olympic swimmer, met Prince Albert of Monaco at a swimming event in 2007 and the couple's marvellous wedding – held in July 2011 – was a highlight of the royal calendar.
In May the Monegasque couple announced they were expecting their first child and the public's interest in the 36-year-old climbed.
Thanks to a rogue tweet by a friend of Charlene's father rumours have started to circulate that Charlene and Albert are expecting twins but the royal couple have not yet commented on the speculation.
Since becoming part of Monaco's royal family Charlene has become known for her elegant style and philanthropic commitment.
Certainly in the past 12 months the former Olympic swimmer has given her late mother-in-law, Princess Grace a run for her money in the style stakes.
Here are some of Charlene's best looks of the past year.
