What Happened To Joshua Bassett, Olivia Rodrigo, Sabrina Carpenter?

According to Us Weekly, the drama between the three Disney stars began when Rodrigo released "Driver's License" in January. Many fans allege that the song is about the rumored drama between her and her co-stars.

Other fans noticed that the singer changed her lyrics from her 2020 teaser song from "brunette" to "blonde," seemingly implying that the woman in the song is Carpenter.

Aside from the hair color, fans also pointed out the lyrics, "She's so much older than me / She's everything I'm insecure about," because Carpenter is three years older than her.

Supporters allege that Rodrigo and Bassett had a romantic relationship last year, but they never publicly confirmed it. The "Anyone Else" hitmaker seemed to have move on with Carpenter when they were spotted attending a protest together. They also wore matching Halloween costumes in 2020.

Following this, Carpenter seemingly clapped back to Rodrigo's number one single by releasing her song in the same month. "Skin" featured the lyrics "maybe 'blonde' was the only rhyme."

At the time of this writing, neither Joshua Bassett, Sabrina Carpenter, and Olivia Rodrigo has publicly confirmed the speculations from their supporters.
