The Duchess of Cambridge made her first solo public engagement by attending a private viewing of the "Lucian Freud Portraits," at the National Portrait Gallery on Wednesday, February 8.

It was the first time Kate Middleton was appearing in public without her husband, Prince William. Prince William is currently on a six-week deployment in the Falkland Islands.

Kate Middleton looked perfect and confident in a grey tweed coat with a black belt and black vertiginous heels.

She is currently the patron of the gallery as part of her charity engagements. Her second solo engagement in scheduled to be in Liverpool on February 14.

Over 100 art works of the acclaimed painter Lucian Freud which were completed over a span of 70 years are on display at the National Portrait Gallery.

The exhibition was planned in close association with the painter himself before his death on July 20, 2011, aged 88.

Lucian Freud's paintings capture the beauty of nudity and many of his paintings are nude portraits of his friends and family.

The event was attended by Lucian Freud's mother Lucie, daughter Bella Freud, fellow artists Frank Auerbach, Francis Bacon, Michael Andrews, John Minton and David Hockney, among others.

The exhibition is open to the public in London from February 9. The US round of the exhibition would be from July 2 to October 28 at the Modern Art Museum of Fort Worth in the US.
