Kate Middleton Prince William Pictures at Gary Barlow Concert

Kate Middleton wore a black and tan dress from Zara and a Ralph Lauren jacket today for a special concert at London's Royal Albert Hall. She joined her husband, Prince William, and her in-laws Prince Charles and Camilla Parker-Bowles for a Gary Barlow show benefiting the Prince's Trust and the Foundation of Prince William and Prince Harry. Camilla was decked out in an ensemble from one of her favorite designers, Anna Valentine.

Gary, who rose to fame as a member of the pop group Take That, apparently addressed Will, Kate, and the royals before commencing his performance. He said, "Good evening to our beautiful royal family." He then went on to do a medley of Take That's greatest hits. Gary is also expected to welcome a few guests to the stage, including X Factor finalist Marcus Collins.
