The couple is currently awaiting the birth of their first child, although Prince William has participated in a busy summer party season. The royal was spotted in June at the wedding of good friend Thomas van Straubenzee (to Lady Melissa Percy), joined by younger brother Prince Harry and sister-in-law Pippa Middleton. The wedding festivities also marked William's birthday weekend—the Prince turned 31.
More recently, the Duke of Cambridge has been hard at work: putting in extra shifts as a search-and-rescue pilot at RAF Valley in Anglesey. With Kate due to give birth this weekend, it has been reported that the helicopter for William's arrival to London left the Anglesey farmhouse where it has been on standby since last Friday.
