Billionaires supporting billionaires!

Melinda French Gates and her daughter Phoebe Gates appear to count themselves among Taylor Swift's billions of fans, evidenced by an Instagram video of the mother-daughter duo singing along to one of the pop star's newest songs.

"@phoebegates and I can't get enough of the new @taylorswift album...anyone else?!" Melinda Gates captioned the Wednesday video.

In the quick clip, the Gates women lip-synch to "Fortnight," the lead single off Swift's most recent album, The Tortured Poet's Department, which was released Friday.

The album has already shattered streaming and sales records as Swift's ever-growing obsessive fan base pores over her Easter egg-filled lyrics and music.

The singer shocked fans three hours after the album dropped by announcing the much-anticipated 16-song collection was actually a double album replete with 31 new tracks.

Thanks to her record-breaking Eras Tour, Swift achieved billionaire status last year, with an estimated net worth of $1.1 billion, joining the rare ranks of female billionaires, of which there are only 337 in the world, according to Forbes.

Melinda French Gates, who co-founded the Bill & Melinda Gates Foundation with her ex-husband and Microsoft founder, is worth an estimated $12.9 billion, per Bloomberg.

The former couple's youngest daughter, Phoebe Gates, 21, reposted the video of her mother in an Instagram story on Wednesday, saying "did not know she was going to post this."

The couple's other daughter, Jennifer Gates, 27, reposted the video on her Instagram, as well, saying, "Cutest (and I have FOMO)."
