Rihanna left The Corinthian Hotel near London's Trafalgar Square earlier this afternoon, heading in the direction of the O2 Arena, where she's due to perform later tonight (February 21, 2012). The R&B star, who's nominated for Best International Female, donned an odd-looking hooded top for the journey.
According to the UK's Daily Mirror, the star had thrown an "all-night party" to celebrate her 24th birthday yesterday, and wore a full-body length hoodie for the journey to the O2 Arena. However, Rihanna was also wearing electric blue stiletto heels - which she had presumably partied in the night before. The Barbadian singer has hit the headlines after recording two remixes with her ex-boyfriend Chris Brown, who was convicted of assaulting her in 2009. The first, a reworking of her track 'Birthday Cake' features racy lyrics which have shocked some fans of the R&B singer. She also lends her voice to a remix of Brown's single 'Turn It Up'. Speculation of a possible reunion has been building for months, and recent reports have suggested the former-couple have been hanging out again. As if to stir up more rumors, Brown tweeted, "Happy birthday Robyn" on Monday.
Later on Monday night, Rihanna appeared to be enjoying herself at the birthday bash, tweeting, "This has to be the funniest night of my life!!! I have not Stopped laughing!!!!!", later adding, "I can't believe I'm pullin an all nighter on my Bday!!!".
