Stage and screen stars Fiona Shaw (Medea, The Testament of Mary) and Kristin Scott Thomas (The Seagull, The Audience) will guest star in the second season of Phoebe Waller-Bridge’s Fleabag, according to Deadline.

Scott Thomas and Shaw's roles in the BBC and Amazon comedy have yet to be announced. The series, produced by All3Media’s Two Brothers Pictures, returns in the spring. The series also features Andrew Scott, Sian Clifford, Olivia Colman, Bill Paterson, Brett Gelman, Jenny Rainsford, and Hugh Skinner.

Waller-Bridge's solo show, which inspired the series of the same name, makes its New York debut at Off-Broadway's SoHo Playhouse beginning February 28. The limited engagement is scheduled through April 7. She is also the creator of the BBC America series Killing Eve, which kicks off its second season in April.
