In this week's Music Minute: Justin Bieber and Rihanna launch world tours and Ariana Grande premieres her new single, Dangerous Woman.

Justin Bieber and Rihanna on tour

Two of pop's biggest stars are on the road right now, with Justin Bieber and Rihanna launching their respective Purpose and Anti world tours over the weekend. Bad boy Bieber kicked off his first night in Seattle with a well-rounded show that featured the singer playing the drums and showing off those dancing skills we all love.

After a two-week delay, Rihanna had a smooth start to her Anti tour in Jacksonville, Florida. The Work singer dazzled the audience with theatrics including flying across the arena on a bridge, acrobatic dancers and – of course – an array of very interesting outfits. RiRi will make her way to the UK in June, while Bieber will arrive in October – so there's still time to get tickets.

The album features the singles Used To Love You, Make Me Like You and a collaboration with Fetty Wap called Asking 4 It. Could this be Gwen's first solo number one album? We'll let you know next week.
