Rihanna seems to be making full use of her time in London as she works on tracks for her new album.
The singer left her London studios late last night where she is working on the follow-up to 2011's 'Talk That Talk'.
''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."
RiRi, who's a regular in terms of filling fans in on her life via social networking site Twitter, posted on Sunday evening (June 17).
She said: "I'm in LONDON bitchesssss," followed shortly by "I didn't wanna leave NY! I kept missing my flights hehehe."
Rihanna will join a host of acts including Jay-Z at this weekend's BBC Hackney Weekend.
The event will be hosted on the Hackney Marshes on June 23-24, with 100,000 lucky ticket holders watching Jay-Z headline on the Saturday night before Rihanna plays a headlining slot the following night.
Entertainmentwise will be coming live from the event so keep updated on the biggest acts of the day over our Twitter and Facebook.
