Former Eurythmics singer Annie Lennox has spoken out about explicit music videos following the topic surfacing in the wake of the Sinead O'Connor and Miley Cyrus debate.

Lennox is the latest artist to add her voice to the public debate on the use of sexuality in music videos after Sinead O'Connor fired off a warning to Miley Cyrus.

O'Connor wrote an open letter to Cyrus, asking her to reject music industry pressure to "prostitute" herself after a series of raunchy performances and music videos, which was responded in kind with Cyrus mocking O'Connor and comparing her to troubled actress Amanda Bynes, who is undergoing treatment in a private facility near Los Angeles on doctors' orders.

O'Connor was horrified that Cyrus would tease her for her past mental health problems, and prompted her to write a second open letter expressing her disbelief.
