A woman has been arrested on suspicion of kissing a painting by American artist Cy Twombly and smudging the bone-white canvas with her lipstick, French judicial officials said Saturday.

Police said they arrested the woman after she kissed the work on Thursday. She is to be tried in a court in the southern city of Avignon on Aug. 16 for "damage to a work of art," judicial officials said.

The painting, which is worth an estimated $2 million, was on display at the Museum of Contemporary Art in Avignon. It is part of an exhibition slated to run at the museum through Sept. 30. Officials did not provide further details on the painting.

Twombly is known for his abstract paintings combining painting and drawing techniques, repetitive lines and the use of graffiti, letters and words.

Born in Lexington, Va., in 1928, Twombly has lived in Italy for nearly a half- century. He won the prestigious Golden Lion award at the Venice Biennale in 2001.
