First it was the Duchess of Cambridge recycling her favourite garments, but it seems Katherine Jenkins is at it too.

The Welsh singer was spotted looking radiant in a red gown at a charity concert last night - the same one she opted for when she appeared on the debut episode of this ITV's Popstar to Operastar just two weeks ago.

She clearly wants to get her money's worth out of the stunning floor length dress which has a cut-out neckline and clearly shows off her curves.

She finished the look on both occasions with matching red lipstick and lashings of mascara.

Earlier this month, Kate Middleton was spotted at a church service marking the 90th birthday of the Duke of Edinburgh, wearing the same periwinkle blue Jacquard coat dress that she donned in 2009 for the wedding of her husband’s close friend, Nicholas van Cutsem.

And a day earlier, the 29-year-old attended the wedding of close friend Sam Waley-Cohen in the same black and white silk cocktail dress that she wore on a night out in London with Pippa in 2007, during her brief split from William.
Katherine Jenkins was performing in front of thousands at the outdoor Music On The Hill charity event in Kent.

It was the first summer concert of the year for the classical star, who kept her fans up to date on Twitter earlier in the day as she did sound checks and got dressed for her big moment.
She even tweeted her set list, which included the Overture from My Fair Lady, I Dreamed a Dream and Hallelujah.
Midway through the concert she tweeted "Part 2 about to start..Shall I sing Singing in the Rain?!Nice 2b back with the gang tho - here with big Ross."
Afterwards she tweeted: "Thanks to everyone who came to the show tonight, braving the rain! You were all troupers and I love you for it!"

The 30-year-old was performing at the first day of the three-day music event at Kings Hill in Kent in aid of the Demelza Hospice Care for Children and The Children's Development Trust.

She was joined by McFly, Stacey Solomon, ABC and X- Factor finalist Ben Mills in the line-up along with The National Symphony Orchestra, conducted by Anthony Inglis.

Red is clearly a favourite for the singer who was spotted in a vibrant red Azzedine Alaia dress and matching hat at Ascot earlier this month.

She attended the event with her fiancé Gethin Jones, the 33-year-old Welsh TV presenter.
