After attending Wednesday night's Opening Ceremonies, William and Kate, both 30, got right to the action on Thursday, cheering on the athletes at some of the very first events of the Games.
Meanwhile, William's brother, Prince Harry, is expected to attend some swimming events at the Paralympics, in what would be his first trip back to the pool since his scandalous adventures in Las Vegas.
William and Kate were outfitted casually Thursday, but were dressed up for Wednesday's Opening Ceremonies – with Kate sporting a coat dress by DAY Birger et Mikkelsen that she has worn on three separate occasions at weddings of friends.
Queen Elizabeth, attending without Duke of Edinburgh, who is recuperating from his recent illness, wore earplugs.
Also announced Thursday: Kate will make her first speech on foreign soil when she visits a hospice in Malaysia as part of a Sept. 11-19 tour with William that will have them jumping from Singapore to Malaysia, the Solomon Islands and the remote island of Tuvalu.
Soon after arriving in Singapore, they are due to have orchids named for them – and one for William's late mother, Princess Diana.
