While She Sleeps and Kelis added to 2014's Reading and Leeds Festival line-up

This year's Reading and Leeds Festival has added a host of new acts to the line-up, which include Sheffield metal band While She Sleeps (pictured left) and 'Milkshake' hitmaker Kelis.

Kelis and Kate Tempest have been confirmed to appear on the Alternative Stage at both locations, While She Sleeps will perform on the Pit Stage, and comedian Seann Walsh will also grace the Alternative Stage in a non-music set.

Last week, the festival made another announcement about new bands and artists joining the impressive bill and Sasha Keable, Bad Rabbits, and The Wytches were all mentioned. Also playing live at the weekend-long event are Macklemore & Ryan Lewis, Imagine Dragons, Die Antwoord, and Vampire Weekend.

Reading and Leeds 2014 is due to take place across the weekend of August 22 - 24.
