On Tuesday, the singer had a day off in between stops on her Bangerz Tour, and she enjoyed the downtime by meeting up with N.Y.C.-based tattoo artist Bang Bang McCurdy.
Cyrus, 21, got two new tattoos, including the words "Love Yer Brain" on her right forearm. "It's from her favorite band, The Flaming Lips," McCurdy told E!.
The second ink job is a small crescent moon on her left arm.
But Cyrus wasn't the only person who got inked. The "Wrecking Ball" singer returned the favor by tattooing the same crescent shape onto McCurdy's thumb. She later Instagrammed a snapshot of herself and the tattoo artist posing with their tongues out, which she captioned, "BFF tats with @bangbangnyc."
Cyrus's other tattoos (around 20 in total) include a portrait of her grandmother, a dreamcatcher, the words "just breathe," quotes from Teddy Roosevelt and a sad cat emoji on her inner lip.
Cyrus isn't the only celeb sporting artwork courtesy of McCurdy. Other high-profile clients include Justin Bieber, Selena Gomez and Demi Lovato.
