Olivia Rodrigo and Sabrina Carpenter were among the headliners for this year’s Lollapalooza . The festival, that will be held in Chicago from July 31 to August 3, is set to feature other major artists like Tyler, the Creator, A$AP Rocky, Doechii , and Luke Combs. When the official lineup was announced, fans quickly shared their thoughts on social media. One person joked on X, saying that their mutual ex, Joshua Bassett , 24, was likely “crashing out” over the news. Another fan referenced the long-standing rumours about Olivia and Sabrina’s supposed feud, adding, “In my head, Olivia Rodrigo and Sabrina Carpenter are still beefing over Joshua Bassett.” Both Olivia and Sabrina expressed their excitement for the festival. Sabrina posted “Awww sh*t” on her Instagram story, while Olivia shared “Wohoo!!!” along with pink hearts and a flower emoji. Olivia’s hit Driver's License was widely believed to be about her breakup with Joshua, which occurred after their time working together on High School Musical: The Musical: The Series , which premiered on Disney+ in 2019. The song, released in January 2021, quickly became a global hit, with many speculating that Joshua was the inspiration behind the emotional lyrics. Fans also believed that Sabrina was the “blonde girl” referenced in the song, particularly after Olivia’s lyrics mention a blonde who “made [her] doubt” her relationship. Olivia, 22, was also younger than Sabrina, 25, which added further fuel to this theory. Sabrina, who also began her career on Disney Channel, was linked to Joshua in mid-2020, though their relationship reportedly ended by 2021. Neither Olivia nor Joshua ever confirmed or denied their romance, leaving much to speculation. Today, Olivia is in a relationship with actor Louis Partridge, while Sabrina had a public romance with actor Barry Keoghan in 2024. Sabrina, however, ended her relationship with Barry earlier this year. Though their past connections to Joshua may have caused tension between the two, it seems that any unresolved issues have been left behind as both have moved forward with their careers.Fans are excited that the Lollapalooza stage might bring them face-to-face. Sabrina released the song Please Please Please last year, which quickly soared up the charts. She was dating Barry at the time. The song is about her hoping her partner doesn't make her look bad, with lines like, "I beg you don't embarrass me / Mother f*****r' and "I heard that you're an actor / So act like a stand up guy." She later spoke of Barry's reaction to the song in her Variety interview . "He loved the song," she said. "He's obsessed with the lyrics, and I'm so grateful for that. I don't want to sound biased, but I think he's one of the best actors of this generation. So getting to see him on the screen with my song as the soundtrack made the video better and all the more special." The pair reportedly broke up to focus on their careers. Like this story?
