dashed back from a romantic skiing trip with his sweetheartKate Middleton
to fulfil royal duties in Cardiff at the weekend.
After six glorious days in the French Alps, enjoying the slopes of the famous Three Valleys skiing region where he'd hired a luxury chalet, the Prince was in the stands at the South Wales city's Millennium Stadium to take in the hotly contested Six Nations championship.
William, who's a royal patron of the Welsh Rugby Union and an avid follower of the game, watched a thrilling showdown in which Ireland beat Wales to take the title.
A number of his royal relatives also caused a flurry of interest by their appearance at another championship match. Prince Harry apparently arrived in the VIP section of Twickenham stadium in London with a beautiful blonde companion, but was later seen devoting all his attention to the action between England and Scotland.
Harry did find time to catch up with his cousin Zara Phillips, though, who cheekily acknowledged his presence by poking her tongue out at him in her typical effervescent style.
She had plenty to celebrate as her partner Mike Tindall helped the home side secure a convincing victory over their Scottish rivals.
