Charli XCX and Jaden and Willow Smith are among acts added to the New Look Wireless Festival line-up.

The 'Boom Clap' hitmaker will be joining the sibling duo at the three-day festival in London's Finsbury Park in July, performing alongside previously announced headliners Drake, Avicii, Kendrick Lamar, David Guetta and Nicki Minaj.

A ''special performance'' from the children of actor Will Smith has been teased by festival organisers, following 14-year-old Willow's breakout 2010 single 'Whip My Hair' and her older brother Jaden's featuring slot on Justin Bieber's hit 'Never Say Never' in the same year.

Clean Bandit collaborator Jess Glynne and 'I Need' singer Maverick Sabre will also perform at the popular event from July 3 - 5, as well as Lethal Bizzle, Travi$ Scott, MNEK and Sinead Harnett.

Other rising stars set to appear at the festival - which is celebrating its 10th anniversary - include Klingande, DJ Mustard, 3Lau, Shakka, Ows, Bad Rabbits, Tove Styrke, Jacob Plant, Ady Suleiman, Nick Brewer, Damage, Tori Kelly, Jermain Jackman and Etta Bond.

The latest update follows the announcement in February that rapper A$AP Rocky would be performing at the central London celebration, along with Belgian singer-songwriter Stromae, rising star PARTYNEXTDOOR, drum and bass producer Netsky and 21-year-old '2 On' hitmaker Tinashe.

Further stars scheduled to appear include Jessie J, Labrinth, Major Lazer, Mary J Blige, Nero, Childish Gambino and 'Rather Be' hitmakers Clean Bandit.
