Boy George and Conor Maynard have been confirmed as acts to perform at the upcoming As One in the Park festival, a gay outdoor festival in London, later this year.

Earlier in March it was confirmed Rylan Clark, former X Factor contestant and Celebrity Big Brother winner, and singer Rita Ora, are to headline at the festival. Marc Vedo will also play a DJ set.

Both singers are to perform at the As One in the Park festival this summer, which is being billed as ”the first credible large-scale gay festival in London for over a decade.”

Other artists announced so far are Katy B, X Factor’s Union J, Offer Nissim and Skin, and more acts are expected to be announced soon.

The event had been held as a night in Vauxhall’s Fire club since 2010, however the organisers of the event, Orange Nation, have said they want to turn it into a whole-day festival which will last from noon to 10pm.

“We felt it was time that London was no longer overlooked when it came to a major gay outdoor entertainment event. We will bring together the cream of London’s gay scene alongside the world’s most internationally renowned gay brands,” said Craig Elder of Orange Nation.

As One in the Park will also feature a presence from cabaret club Madame JoJo’s, lesbian festival L Fest, and gay bar Ku Bar.

The event will have five stages, and four indoor arenas, with further acts and DJs to be announced soon.

Some other brands involved in the festival are Delooded, Shadow Lounge, Bearracuda, Madame JoJo’s, Findhrr, Girl Action, L Fest, Mint, Code, Ku Bar, Rupert Street and Comptons, reports Digital Spy.
