The U2 frontman was spotted with two 19-year-old women while vacationing in St-Tropez last month.
The photographs, in which Bono is seen with his arms around the women, were recently published on the girls’ Facebook page.
Bono was on vacation with his friend, Simon Carmody, an Irish musician, when he met the American student Andrea Feick and her best friend, Hannah Emerson of England.
Feick said that the two girls partied with Bono and Carmody at the Nikki Beach hotel, and also on a yacht owned by The Edge, but insisted that their time spent together was purely platonic.
The U2 singer and his wife, Ali, have been happily married for 26 years.
