Katharine McPhee will leave the West End production of Waitress in June, it has been confirmed.
McPhee, who previously played the role on Broadway, originated the lead role of Jenna in the West End production at the Adelphi Theatre.
She will play her final performance on 15 June, with her successor in the role to be announced soon.
The production currently stars McPhee as Jenna, Jack McBrayer as Ogie, Marisha Wallace as Becky, Laura Baldwin as Dawn, Peter Hannah as Earl, David Hunter as Dr Pomatter and Shaun Prendergast as Old Joe.
Sara Bareilles' songs feature in the piece, which is based on the 2007 film by Adrienne Shelly and has a book by Jessie Nelson. The show tells of a waitress and avid baker in a small town working in a diner who is stuck in a toxic relationship.
The show is directed by Diane Paulus, with choreography from Lorin Latarro, lighting from Ken Billington and designs from Scott Pask.
Waitress is currently booking until 19 October.
