US punk rocker Patti Smith shook hands with Pope Francis at a general audience in St Peter's Square on Wednesday, saying afterwards she found the new pontiff "very interesting" and "liked him a lot".
Wearing a black beanie hat and an oversized brown coat, Smith and the pope appeared to exchange a few words in the square and the pope was seen laughing.
Smith, who is not a Catholic but followed the conclave in the news, said the pope had shown courage in naming himself after St Francis of Assisi.
The singer, who is in Rome for a series of concerts, said the saint represented humility, the renunciation of materialism and a love of nature.
Smith became a leading member of the New York punk rock movement following the release of her debut album Horses in 1975.
