UK premiere of 'War Horse' has Duke and Duchess of Cambridge sharing the red carpet with film star Joey

The Duke and Duchess of Cambridge shared the red carpet with an actual horse at Sunday's charity premiere of Steven Spielberg's War Horse.

Spielberg was honored to have the royals nearly upstage his four-legged star. Speaking with the BBC Spielberg said, "This is my first royal premiere for the Duke and Duchess, having done them before for the Queen and the Queen Mother. This is a wonderful occasion tonight. This is so exciting. I get a buzz."

Despite the drizzle, the event brought a chivalrous prince and his bride out of hiding. Held in London's Leicester Square, the premiere was for the the Foundation of Prince William and Prince Harry -- the princes' charity. One of the many horses who played the star Joey in the film also appeared on the red carpet, a first for royal premieres.

No stranger to the style press, Kate's Alice of Temperly LLD (Long Lace Dress) proves the Duchess is sticking with what makes her comfortable. Commenting on her dress, The Mirror noted the stye was "modest and demure in cut (NB the long-sleeves and delicate accessorizing) but on-trend and (dare we say it) a little bit sexy in fabric. Hell, it even features a v-neck - what will Her Maj say!?"

We wonder if Kate is jealous of Prince William's ease of dressing -- his double breasted tuxedo looks fantastic and no one will ever judge him for wearing it twice in a row.

The Daily Mail reports other guests of honor included actors Jeremy Irvine, Emily Watson, and Cheska Hull, as well as 600 serving and ex-serving military personnel and their families and beneficiaries of military charities, with which the princes' foundation has been working.

"The servicemen and women have been invited from The Duke of Cambridge’s regiments, including RAF Search and Rescue, Household Cavalry, Irish Guards, Royal Air Force Coningsby, Scotland Royal Naval Command and Submarines Royal Naval Command," the Daily Mail said.

After the premiere, wealthy benefactors were invited to attend a dinner for the princes' foundation. For a mere £10,000 a head ticket holders would have the opportunity to mingle with the Duke and Duchess, Spielberg, as well as cast members. The Daily Mail reported on the charity dinner several weeks ago saying that "despite the glamour the evening promises, some eyebrows have been raised, even among more wealthy circles, by the cost of the tickets."

Proceeds from the dinner were said to benefit military charities as well as pay for service members to attend the premiere.
