The company have flown over Broadway star Marisha Wallace to cover the role of Effie White with Karen Mav
In a tweet it was confirmed that Amber Riley, who has been off for several performances over the festive period, has been diagnosed with pneumonia, along with other members of the cast.
Audiences have missed out on seeing Riley while she recovers. Instead, Broadway star Marisha Wallace has been flown over to the UK to take on the role alongside alternate Effie Karen Mav.
Wallace has performed as Effie White in the US and was part of the cast of Something Rotten on Broadway.
The statement read that Riley was in the final stages of recovery and is expected to return in the next few days.

Dreamgirls is currently booking at the Savoy Theatre until 6 May.
