Rihanna has confirmed plans to release her 777 tour documentary on DVD.

In November last year, the superstar singer played seven shows in seven countries in just a week as she flew around the world.

She invited fans and journalists with her on the trip, which visited cities such as London and Berlin.

The 'Stay' star is due to show a documentary of the tour on US TV's Fox on May 6 before it gets a full DVD release.

The public will be available to buy the 777 documentary from May 7.

As previously reported, Rihanna recently treated fans to a sultry topless photo on Instagram as the US leg of her Diamonds world tour continues.
