Olivia Rodrigo’s third studio album, “You Seem Pretty Sad for a Girl So in Love,” drops June 12 via Geffen and has already generated strong speculation around guest features following the April announcement and the release of lead single “drop dead.” Traders are pricing in artists whose vocal styles, critical acclaim, and prior industry connections align with Rodrigo’s emo-pop sound and producer Dan Nigro’s history of high-profile collaborations. Leading contenders include Lorde, Phoebe Bridgers, and Billie Eilish, whose recent output and mutual admiration in interviews have fueled market momentum. The short runway to release leaves room for last-minute announcements or leaks to shift sentiment quickly, while the album’s streaming performance and any surprise co-writes could further clarify which names ultimately appear.
