Rihanna is reportedly working on new material during her trip to London.

The singer has allegedly booked three days in the studio with British producers ahead of her headline slot at Radio 1's Hackney Weekend on Sunday (June 24).

"Rihanna is working with Marina and the Diamonds' boyfriend Burns, a Brighton-based producer who is good mates with Calvin Harris," a source told The Mirror.

"They've booked three days in the studio, which they'll fit around him doing some work with Kelis. Rihanna's also working with Nicky Romero, another DJ and pal of Calvin."

Rihanna has previously worked with Harris on her international hit 'We Found Love' and new single 'Where Have You Been'.

The Bajan performer recently confirmed that she will embark on a new world tour in 2013 and promised fans that it will be "bigger than anything [she's ever] done".

Can't this woman just go away already!?
