Justin Timberlake and Jay-Z will headline this summer's Wireless Festival as it moves to its new home at the Olympic Park in east London.
Sexyback singer Timberlake , making his musical comeback after a spell of acting in films such as The Social Network will be playing his only UK festival performance of the year. Rapper Jay-Z will be playing his only UK date when he performs at the Queen Elizabeth Olympic Park in July.
Also on the bill for the July 12 and 13 shows will be Snoop Dog, Rita Ora and Emeli Sande.Tickets for Wireless go on sale on Friday.
The organisers of London's Bloc festival have issued a statement to apologise for the cancellation of the event.
The Met Police blamed poor weather conditions for the decision to close the venue, which was taken in the early hours of Saturday morning.
The event took place at The London Pleasure Gardens, a temporary event space in the East End. Fans paid up to £125 a ticket to see stars like Snoop Dogg and Orbital.
Many complained of overcrowding from the start, with long queues to get into the festival, compounded by equally long waits trying to get into individual tents on site.
Organisers have issued a statement on their website which reads: "We are so sorry what we couldn't deliver the experience we had planned."
They also say they are working to ensure that everyone will be refunded for their tickets.
Music fans have been left hugely disappointed after they were refused entry into the Wireless Festival after accidentally buying fake tickets.
Live Nation, promoters of this weekend's festival, said many people who had bought tickets from websites such as Gumtree and eBay have been refused entry as their tickets were fake.
This caused bitter disappointment for many who had been looking forward to the event, however others weren't so sympathetic.
