Justin Timberlake was joined on stage by Jay-Z at the Wireless festival last night.
The singer was the headliner for the first night of the festival in London, and his 'Suit & Tie' collaborator joined him for a live rendition of their hit.
Justin's wife Jessica Biel was joined by the likes of Snoop Lion, Rita Ora, Frank Ocean and magician Dynamo as she watched her husband go through an exciting performance seeing him play guitar and piano during the set.
Justin Timberlake brought SexyBack to London as he opened the Wireless festival in London.
The chart-topping Suit And Tie star, in a black shirt and trousers with a trilby hat, kicked off his set with 'Like I Love You' armed with a guitar before taking the crowds on a 90-minute funk-filled journey.
The 32-year-old singer and actor, backed by his band The Tennessee Kids, topped the bill at London's Olympic Park on the festival's first night, which included earlier sets from Snoop Dogg, now known as Snoop Lion, John Legend, Frank Ocean and Miguel.
Timberlake, who also showed off his various talents by playing the piano, beatboxing and dance moves, got festival-goers up on their feet with crowdpleasers 'Senorita', 'Rock Your Body', 'Cry Me A River' and 'Summer Love', before performing tracks from his latest album 'The 20/20 Experience' including 'Mirrors'.
"London, you alright? I know you've been here all day but we are starting the party right now," he said.
"I am slightly p*****. I can't believe you are all here right now. We are here now. I promise it won't be so long again."
Timberlake was then joined by rap superstar Jay-Z - who is the headlining act on the main stage tomorrow - on 'Suit And Tie' before closing with 'SexyBack'.
The duo will then close the festival together, performing as Legends Of The Summer, on Sunday.
This is the latest major UK gig for the US singer - who is married to actress Jessica Biel - following his performance at the Capital FM Summertime Ball.
He previously played an intimate gig at the Roundhouse in north London in February, after performing at the Brit Awards 2013 - his first shows in six years after a hiatus from music.
