The 55-year-old star is currently touring the UK with a stage version of her hit sitcom 'Birds of a Feather' with longrunning co-stars Pauline Quirke and Lesley Joseph, but the show at the Congress Theatre in Eastbourne was halted when she fell ill, reported Contactmusic.
Robson was forced to run off during one scene, before returning to the stage to carry on with the rest of the show.
After the production, Robson took to her Twitter page to thank the audience for their patience.
