Rihanna celebrated her birthday on a romantic holiday with Chris Brown.
The Grammy-winning singer turned 25 on Wednesday and was pictured spending the day walking hand-in-hand with the 23-year-old rapper on a beach in Hawaii.
Rihanna tweeted a picture of herself with Chris and wrote: "Pour it up pour it up! #birthdaybehaviour"
The Barbadian beauty raised eyebrows with her birthday attire, wearing fish-net trousers over her red thong bikini bottoms, leaving very little to the imagination.
Rihanna and Chris went public with their reconciliation at the end of last year.
They split in 2009 after Chris was charged with assaulting the star.
