Lily Donoghue plays Lacie Barone, Taylor’s sorority sister, in The Summer I Turned Pretty season 3.
Lacie is a recurring character whose conversation creates one of the season’s major relationship revelations. In the premiere, Belly overhears Lacie bragging about hooking up with Jeremiah in Cabo during spring break, prompting Belly to confront Jeremiah.
The character belongs to Taylor’s college social circle, which makes her different from Belly’s roommate Anika. Her connection to Jeremiah also places her directly inside the season’s central conflict involving trust, engagement, and unresolved feelings.
Lily Donoghue was one of the performers added in recurring roles for the third season. She should not be confused with Isabella Briggs, who plays Steven’s co-worker Denise, or Kristen Connolly, who plays Taylor’s mother, Lucinda Jewel.
