Kate Middleton makes a surprise appearance at the horse races

Prince William and Kate Middleton made a rare and surprising appearance at the horse races today. The Prince and his pregnant wife arrived to the cheers of fans during a horse race at Cheltenham Festival which is located approx. 120 miles outside of London.

The Duchess of Cambridge looked radiant in a camel coloured coat, which, unfortunately, covered her ever-growing baby-bump.

According to People, Middleton was spotted re-using another one of her fashion staples, a brown Lock and Co Betty Boop hat, which she reportedly wore to a close friends wedding in Switzerland.

The Prince and Duchess werent the only royals in attendance, according to People, Zara Phillips mum, Princess Anne, was also there holding court.

Despite her pregnancy, this is just one event that the Duchess has on her schedule. Also confirmed: Middleton is also set to attend a volunteer training event at Great Tower Scout Activity Centre in Cumbria, on Friday, March 22.

According to Scouts.org, the Duchess will attend the event together with around 20 other adult volunteers, learning new skills that will support her in her role as an occasional helper at her local Scout Group.
