Billie Eilish has already started working on her eagerly awaited sophomore album.

Last year, the 18-year-old singer-songwriter released her highly acclaimed debut album, When We All Fall Asleep, Where Do We Go?, and her brother Finneas O'Connell - who works as her producer - has confirmed the pair are already working on a follow-up.

Speaking to Vulture magazine, he said: "We've started working on the new album, and I think the best thing we can do is stay out of our own way. The first album was pretty pure in its intention.

"Our only target was to make an album that we liked, to play live. I think that's all we're gonna do for the second. All the other things are side effects. You can't aim for those."

Last year, Eilish's brother said they would be heading in an "experimental" direction following the success of their debut record, which saw her bag multiple awards, including becoming the youngest artist to sweep the main four categories at this year's Grammys.

Finneas explained: "I think so far, in album two... there's just a lot of stories we felt we didn't get to tell yet. 

"We're just trying to tell all those and we're being a little bit experimental. I think if you're not trying to change things a little bit, you're not evolving.

"So I think we're just trying to embrace everything that we are proud of in our music and also just try new things and experiment and give people stuff to look forward to."

Eilish's Where Do We Go? World Tour has been among a host of those postponed due to the coronavirus outbreak.

The 'Bad Guy' hitmaker began her tour on March 9 in Miami, Florida, but was subsequently forced to axe all remaining dates in March due to the spread of the global pandemic.

She said: "I'm so sad to do this but we need to postpone these dates to keep everyone safe. We'll let you know when they can be rescheduled. Please keep yourselves healthy. I love you."

As of the time of writing, the superstar's remaining North American tour dates are actively being rescheduled and are set to be announced soon. All tickets will be honored for the new tour dates. All UK shows, which are set to kick off later this year in July, so far remain unaffected.
