The 'Can't Say No' singer will play at the festival - held at London's Queen Elizabeth Olympic Park on July 12, 13 and 14 - on the same day as the 'Suit and Tie' singer, and has devised and ingenious plot to meet him.
Speaking at the Yahoo! Wireless festiva Launch Party in London last night (19.06.13), he told BANG Showbiz: ''Because I'm on the same day as Justin, I'm planning on hiding behind the drum kit after my set, so I can still be on stage when he comes on.''
Conor partied into the night at the May Fair hotel, alongside celebrities including Amelia Lily, Dionne Bromfield and Misha B. Party guests were entertained by DJs and live acts including dubstep group Monsta and singer Bluey Robinson.
Wireless festival will he headlined by Justin Timberlake on July 12, Jay-Z on July 13 and both artists together on July 14, marking the start of their Legends of the Summer tour.
