Kelsey Pierce (Book Character)

Kelsey Pierce was Spencer's classmate at Penn over the summer. It's revealed in the prologue of Ruthless that she and Spencer used drugs and were arrested. Spencer asks Hanna to help her frame Kelsey for using drugs, and Kelsey is arrested, unknowingly framed. The next time Spencer sees Kelsey after framing her is when Amelia invites the St. Agnes Charity Chamber Music Group over to their house. Spencer then has a flashback of Phineas, a boy Kelsey and Spencer meet at a bar, giving them drugs Kelsey is later arrested for. Emily also has a past with Kelsey, but doesn't immediately recognize her name, since Kelsey introduced herself as Kay. Emily seemed to have a crush on Kelsey, describing her as "a sexier, green-haired version of Ariel from The Little Mermaid". Kelsey may be bisexual, as at the party she meets Emily at, she kisses Emily.

Appearence
Kelsey is described as having "cinammon-red hair" and "sparkling green eyes". She goes to St. Agnes, the same school that Spencer's step-sister, Amelia Pennythistle, goes to.
