Kate looks great - more photos are below in the gallery.

Kate Middleton showed off in a red dress at the Jubilee Thames River Pageant.

Have we seen it before?

Yes! There were no new clothes for the thrifty Duchess of Cambridge as Kate wore a 2011 McQueen dress and recycled her shoes and hat for the extravagant event.

Meanwhile Britain's Prince Charles has been dubbed a "cool guy".

The future king went to meet Gary Barlow to discuss plans for the official Diamond Jubilee single 'Sing' - which will celebrate his mother Queen Elizabeth's 60 years on the throne and features performers from throughout the Commonwealth - and the Take That frontman was very impressed with his knowledge of music.

He said: "Prince Charles was our first port of call. I was looking for guidance on what the queen liked musically and the kind of artists she listened to.

"He came in with a stack of CDs and said, 'This is my music collection.' It was really varied. But there was a lot of music from Africa and from Jamaica and it was he who said, 'If you're going to do this and you want the queen to live it, you've got to include all these people because that is what she's most proud of.'

"He's such good company, Prince Charles. He has a fantastic sense of humor. He's a cool guy."

Gary worked on the song with Lord Andrew Lloyd Webber and he says he's very proud of the track, which he wrote in Kenya's Aberdare National Park, where the queen first learned of her father's death and became monarch.

He said: "It was just so fitting and quite beautiful, I felt, to write the words to the song at the spot where the queen's personal journey began."
