Further acts to be announced.
The UK chart-topper follows her sell-out spring tour with a Wireless appearance.
While Outkast are also set to headline Bestival, on the Isle of Wight, Wireless will be Kanye and Bruno's only UK live appearances of the year.
Ellie Goulding started the year on a high. Her million-selling album Halcyon Days hit no.1 and she's officially the second-biggest selling artist in the UK in 2013 - having amassed over 2.5 million sales. Meanwhile, her UK Arena tour in March has completely sold out.
Interestingly, Drake's recent album, Nothing Was The Same, features Jay Z on the track Pound Cake/Paris Morton Music 2, which also contains elements from Ellie Goulding's Don't Say A Word.
The line-up for the festival was officially announced at a special Wireless Launch Party on 28 January at Birmingham's O2 Academy. Among those appearing were rising UK star, Ella Eyre. The BBC Sound of 2014 shortlisted singer is best known for her collaborations with Rudimental (no1 single, Waiting All Night). She's also worked with both Naughty Boy, Wiz Khalifa, Bastille and Tinie Tempah. Rudimental also helped launch the career of Yorkshireman John Newman, who guested on Feel The Love - another no 1 track for the quartet.
2014 marks Wireless' 10th anniversary with previous headliners including Justin Timberlake and Jay-Z (2013), Rihanna and Drake (2012), and Black Eyed Peas and Pulp (2011). The very first festival featured Basement Jaxx, Moby, New Order, Keane and Kasabian.
The London version of the festival will take place in Finsbury Park for the first time with Kanye (Fri), Drake (Sat) and Bruno Mars (Sun).
