Billie Eilish performs at 'unbelievably beautiful' Cloud Forest in Singapore's Gardens by the Bay

Billie Eilish made the most of her trip to Singapore in August, not only holding a concert for the Happier Than Ever world tour, but also filming two live performances at Gardens by the Bay.

Videos of the performances of her new songs TV and The 30th from her surprise release Guitar Songs, were released on Thursday (Aug 22) and both are already trending on the music chart for YouTube.

They show Eilish and her brother Finneas doing an acoustic performance, with the 20-year-old singer's hauntingly delicate vocals lilting through the lush greenery of the Cloud Forest.

The Cloud Forest features a mountain of greenery and is home to one of the world’s tallest indoor waterfalls.

"Got to sing tv and the 30th in Singapore’s unbelievably beautiful Cloud Forest," wrote Eilish in an Instagram snippet.

The videos were shot in partnership with the Singapore Tourism Board as part of its SingapoReimagine campaign, and directed by Singapore filmmaker Choann.

“Singapore was one of the first places I ever went on tour. I was only there for a day and absolutely fell in love with it,” said Eilish in a statement.

“The Cloud Forest is one of the most beautiful places I’ve ever seen in my life. These two songs really are just very important to me in a lot of ways. I feel really connected to them and very personally protective over them, and I wanted to have some sort of piece with the songs that felt really intimate and personal. It just felt really comfortable to do it in a place as beautiful at the Cloud Forest.”

In a note on Instagram, director Choann wrote: "I chose the Cloud Forest because these songs were so personal and intimate, and I wanted to bring out their themes of existential anxiety through the idea of isolating Billie and her brother in a giant snowglobe-like structure. Billie is also a strong environmental advocate, so Gardens by the Bay was a perfect fit."
