They're performing a highly anticipated song together at tomorrow's Brit Awards - but Disclosure and Lorde haven't yet met face-to-face.

The British electro act are performing with the Kiwi pop star at the UK-based ceremony, but the duo admitted to the Daily Star they hadn't yet met her.

Instead, band member Howard Lawrence told the publication they'd been organising their performance over the phone and via Skype.

"It's been tough getting things ready as we've been on the road," Lawrence said.


"So we've been constantly on the phone with Lorde, organising stuff. It was somebody else's idea to hook up so we haven't even met her yet.

"We've only been able to communicate remotely or through Skype because we've been so far away."

He said they'd have a "a few hours" to rehearse whatever they wanted to do at the ceremony.

"We get a few hours' rehearsal before the performance so hopefully it will come together."

Lorde is up for Best International Female Solo Artist at the Brits, which screen on UK TV at 8.30pm, Thursday night.

It's Lorde's second-biggest awards ceremony performance this year after the Grammys, at which she won two awards.
