Londoners might catch a glimpse of Rihanna out partying tonight (February 20th) as the singer celebrates her 24th birthday in the capital.

The singer, who is rumoured to be reuniting with ex-boyfriend Chris Brown, touched down in the city for rehearsals ahead of the Brit Awards, due to be aired tomorrow night.

The star carried off her quirky style outside a London hotel today, with the Daily Mail picturing her in a college baseball jacket, denim hotpants, silver necklace and boots.

Her look was completed with red-ribbon suspenders, over-sized sunglasses and her new blonde mop swept neatly back in an up-do.

Rihanna took to Twitter to say: “Brit rehearsal went smoove! Next stop, set up studio in a hotel room! I’ll be turning 24 making mu$ic!!!” [sic]

She split from Brown in 2009 after a feud turned physical and the female singer ended up badly bruised in a case of domestic abuse.

Controversy arose last week after Brown received a Grammy Award, with female Twitter fans using the site to suggest they would accept his abusive behaviour if it meant being in a relationship with him.
