Billie Eilish shows off her new sneakers in the desert as she promotes her collaboration with Nike

Billie Eilish took to Instagram to share new photos promoting her collaboration with Nike on Tuesday.

The Bad Guy songstress, 20, posed in a variety of neutral and mixed-material outfits to announce the arrival of two new sneakers. In April, the Happier Than Ever singer announced her collaboration with the sportswear brand to release her 'reimagined' Air Force 1s and her own line of apparel.

The Academy Award-winning songwriter wrote in her Instagram caption: "my new [Nike] AF1 low is hereee" and "hope you love both the [two new colors] mushroom and sequoia".

The star - who is dating The Neighbourhood vocalist Jesse Rutherford, 31 - showed off her kicks with chocolate leg warmers with lace detailing at the bottom.

In the barren desert, she donned winter wear-inspired outfit with tan baggy pants and an oversized camel jacket with a warm brown collar.

All bundled up, she sported a camouflage-patterned top and laid down in a concrete tube in the sand dunes. Check out the post below!
