The singer released the clip - which sees her stripping to her underwear in a hotel room - as a thank you to fans ahead of the final show on her 'Black Star' tour.

Avril Lavigne and Brody Jenner have reportedly split up.

The singer and the reality TV star - who had been dating for almost two years - have decided to call time on their relationship because they couldn't agree on their future.

A source told Life & Style magazine: "They decided to end their relationship. It wasn't working out, and they wanted to go their separate ways.

"She wanted to settle down, but he wasn't exactly ready. They had been having problems starting in the summer with her tour because she was on the road all the time. It put a strain on their relationship."
