The Duchess of Cambridge and William were ready to rock Tuesday night in London.

The newlyweds attended a special charity concert along with Prince Charles and Camilla at the Royal Albert Hall, featuring a performance by Gary Barlow, the lead singer of British pop act Take That.

Kate, 29, sported a Zara dress and Ralph Lauren jacket to the show – where she and William were also joined by Camilla's daughters, Laura Lopes and Sara Parker Bowles.

As they strolled the red carpet, Kate had a quiet chuckle with William, 29, and also chatted with Camilla, who was in an Anna Valentine dress.

Once inside the venue for the show, which benefits both Charles's charity, the Prince's Trust, and the Foundation of Prince William and Prince Harry (of which Kate is also now a patron), the young couple took their place at the front of the royal box as the sold-out crowd loudly cheered for them.

Barlow, who is arranging shows at Buckingham Palace for the Queen's Diamond Jubilee next year, waved at the royals after singing the opening verses of Take That's "The Greatest Day." And before the concert he got some time to chat with the guests of honor. "I do hope you enjoy tonight and I hope it's not too loud for you," he told them.

Replied William, "The louder the better."
