The way 21-year-old singer and songwriter Billie Eilish spends her millions might surprise you.

While Forbes puts her net worth at an estimated $53 million, she’s not one to splash the cash.

She earned her fortune via two studio albums and touring.

2023’s Happier Than Ever, The World Tour was the highest-ranking female-led tour of 2022.

It made over $106 million in revenue, giving Taylor Swift a literal run for her money.

She also rakes in the cash via brand endorsements, writing a book, acting, and an AppleTV documentary.

In fact, the investments of the seven-time Grammy Award winner are as kooky and offbeat as her style.

Despite the money in the bank, however, she seems to have emotional connections to her fleet of supercars.

She once posted a photo of herself on Instagram standing next to an eye-wateringly expensive blue McLaren 600LT.

However, it turns out the vehicle wasn’t hers.

What we do know is that Billie Eilish once bought a Dodge Challenger SRT Hellcat.

It’s thought to have a cost in the region of $60,000 to $83,000.

That’s relatively reasonably priced for a young millionaire and comparatively less than other young people with money.

She frequently shares pictures of it on Instagram.

Named ‘Baby Mama’, the coveted Dodge Challenger is Billie’s first car.

It featured prominently in her music video for the song Everything I Wanted.

As a five-year-old car, though, the Challenger has already suffered from some problems.

When the six-year-old car is in need of repairs and exterior touch-ups, Billie Eilish sends it to the famed auto shop, RDB LA.

The Bad Guy singer also has a Chevrolet Suburban, of which Rihanna is also a fan, and a Mazda 5 minivan, which she uses as a daily driver.

A Dirt article published in October 2021 claimed that Billie Eilish secretly bought a Glendale horse ranch for $2.3 million in 2019.

The article points to several pieces of evidence.

These include Eilish’s song, NDA, in which she states that she “bought a secret house when I was seventeen.”.

It was bought by a trust linked to Eilish’s business managers.

The real estate agent representing the buyer is the same person that Eilish’s brother has used to buy real estate.

However, ownership of the ranch remains shrouded in mystery – it’s claimed by some she still lives with her parents in LA.

According to reports, the ranch is designed for horses – she should probably give Robert Downey Jr a call for animal-care tips.

It boasts stables with four stalls, an arena, and a feed room.

For humans and other animals, the property also has a swimming pool, a sundeck, a goat pen, a paddock, a 2,100 square foot single-story ranch house, a guesthouse, and “a horse-keeper’s apartment”.

It’s also claimed that she spends on watches and fine jewellery that she layers.

Her favorite brands include Chanel, Gucci, Bvlgari, and Chopard.

For watches she opts for brands that are an $8,000 minimum like Rado, Cartier, IWC Schaffhausen, and Hermès.
