The actresses, who play mother and daughter Cora Crawley the Countess of Grantham and Lady Edith Crawley looked a far cry from their onscreen characters.

Elizabeth, 51, looked great in a navy peplum dress, over which she wore a bright blue quilted coat.

The pretty actress added a splash of colour with bright red lipstick, as she happily posed for the cameras.

Laura, who plays her somewhat dowdy daughter, cut a very stylish figure in a chic beige trench coat, underneath which she wore an all black outfit with black heels.

Also from the ITV period drama was the women's co-star Brendan Coyle, who plays Bates, attended with his girlfriend Joy Harrison.

Homeland star Damian Lewis was wrapped up for the cold weather with his actress wife Helen McCrory.

Another couple making a date night of the evening were Duran Duran's Simon Le Bon and his model wife Yasmin.

Comedienne Ruby Wax made it a girls' night out as she arrived with actress pal Frances Barber.

The show's first night didn't get off to the best of starts as it began 45 minutes late due to technical problems, but no doubt once it did it delighted the host of British stars attending.

The Book Of Mormon stars Gavin Creel and Jared Gertner as Elder Price and Elder Cunningham, two Mormon boys sent on a mission to Uganda.

Gavin and Jared recently played the roles in the Los Angeles production, which was written by Parker, Stone and Avenue Q's co-creator Robert Lopez.
