Prince William says Kate's cooking is 'the reason I'm so skinny' on glamorous date night

The Duke and Duchess of Cambridge were quite the dapper duo on Wednesday night (June 22) as they attended a glitzy gala together. Leaving their little one Prince George and Princess Charlotte at home, the royals were the guests of honour at the glamorous affair.

KATE WOWS IN FAMILIAR JENNY PACKHAM GOWN

The night was held to support the East Anglia's Children's Hospices charity, of which Kate is patron. Titled A Taste of Norfolk, it marked the charity's recent appeal to raise funds for a new hospice, The Nook.

The Duchess courted plenty of attention in her gorgeous, pale-pink sequinned Jenny Packham gown. Fans were quick to recognize the dress - Kate debuted it in London in 2011. William, 34, was his wife's perfect partner, looking sharp in a smart tuxedo.

KATE'S MOST GORGEOUS EVENING LOOKS

And it seems that William was particularly looking forward to the special night out, which featured a special five-course meal prepared by five Michelin-starred chefs, as it meant a break from Kate's usual dinners.

"William has to put up with my cooking most of the time," Kate, 34, told the chefs. "It's the reason I'm so skinny," joked William.

The exclusive event was hosted by David Cholmondeley, the 7th Marquess of Cholmondeley and his wife Sarah, Marchioness of Cholmondeley, at their country home Houghton Hall in Norfolk.

Joining fellow guests at the stunning location, William and Kate began their date night with a champagne reception. Musical entertainment was provided by the Jefford Brothers and Sam Aldersey-Williams, while 22-year-old magician Archie Manners also made an appearance.

Guests later feasted on the sumptuous five-course meal, cooked and created by five world-renowned chefs: Galton Blackiston, Sat Bains, Claude Bosi, Tom Kerridge and Mark Edwards.

After dinner, the invitees were treated to a performance from the charity's Treehouse Choir. Author and EACH ambassador Anthony Horowitz OBE, and host The Marquess of Cholmondeley, then delivered speeches.

Kate's association with EACH means a great deal to her. The mom of two has been royal patron of EACH since January 2012, and her very first public speech in March that same year was for the opening of the Treehouse, a children's hospice opened by the charity.

Just a few months ago she stepped out on behalf of EACH to open a new shop in Holt, Norfolk, a short distance from Anmer Hall, the country home she shares with William, George and Charlotte.
