The cult of the celebrity 'selfie' - where stars post a (usually) flattering self-portrait of themselves on twitter - shows no signs of abating. More than an ego-trip, the celebrity selfie is a star at the most candid they'll ever be, offering a more personal glimpse into their lives (albeit through an Instagram filter), and is even used to break news (from Miley Cyrus and her haircut to Matthew McConaughey and his engagement).
Evolving beyond the classic 'Duck face' pout, hand on hip mirror shot, celebrity selfies now come in many guises, and are surprisingly addictive, from Florence Welch and Alexa Chung's daily outfit choices, to Beyonce and Rihanna's seemingly endless holiday snaps, and ahem Craig David's obsession with the gym.
So for a light mid-afternoon distraction, take a look at our pick of the self-posers on twitter - with plenty of inspiration for your own 'selfies' if you need them...
