It's ultimate bad girl RiRi's birthday, so The Old Queen's Head in Islington are throwing her a big birthday bash. And even though – let's be frank – Rihanna probably won't show, that doesn't mean you guys can't have a ton of fun in her honour. Bounce along to all her classic hits, as well as a cavalcade of other R&B bangers. Come Mr. DJ won't you turn the music up. Also, there's cake. Which is really the most important part of any event, wouldn't you agree? Rihanna fancy dress is more than encouraged. Over 18s only. Valid ID required. Last guaranteed entry: 9:30pm.
