A new self-portrait by artist Lucian Freud, featuring a naked woman, has gone on display for the first time.
It shows the 83-year-old artist painting in his studio with the woman clutching his leg.
The work - titled The Painter Surprised by a Naked Admirer - went on display at London's National Portrait Gallery on Wednesday for three weeks.
It will then form part of a retrospective exhibition in Venice, Italy, later this year.
Gallery director Sandy Nairne said: "I am delighted that Lucian Freud has chosen to give visitors to the National Portrait Gallery the first chance to see his new painting. It is a special occasion."
A spokesman for the gallery said the identity of the woman in the picture has not been revealed.
Following its display in London, The Painter Surprised by a Naked Admirer will go to Venice's Museo Correr for an exhibition this summer.
Freud, the grandson of famed psychiatrist Sigmund Freud, also recently painted supermodel Kate Moss.
Lucian Freud's image of Kate Moss sold for £3.9m
The almost life-size nude, called Naked Portrait 2002, was painted while Moss was pregnant with daughter Lila Grace and went on to fetch £3.9m at auction.
A 1967 self-portrait by Freud will go on display at the National Portrait Gallery's major autumn exhibition, Self Portrait Renaissance to Contemporary.
It will hang alongside works by legends from the early 15th Century to the present day including Rembrandt, Reynolds, Van Gogh and Bacon.
