'Taking to Tumblr, 'Neon' hitmaker Queen Of Hearts has 'revealed' that she'll be singing some of her songs in Hyde Park as part of the BT London Live Olympics tie-in festival thing.

"I’ll be per­form­ing twice on Saturday 11th August — once at 15.40, and again at 19.50, and I’ll be unveiling some brand new material espe­cially," she said.

Perhaps she's got an Olympic-themed single like everyone else?

"It’s going to be a great day, and I’m so excited to be involved in London 2012 in some way — it would be great to see as many of you guys down there as possible, so please put it in the diary!" she pleaded.

A lot of popstars are playing this festival thing and there's more info about all that here. It's free if that helps at all.
