The exclusive Claridge's hotel has been widely criticised for asking a woman to cover herself with a "ridiculous shroud" while breastfeeding her three-month-old daughter.
Lousie Burns said she burst into tears when staff members at the five-star venue asked her to cover herself and her baby with an oversized napkin in order to avoid "causing offence" to other guests.
The mother-of-three was enjoying afternoon tea in the main Tea Room on Monday when the incident happened.
Ms Burns, who is married to actor Nick Burns - best known for the comic character Nathan Barley, told The Evening Standard waiters rushed over and covered her when she began feeding her daughter.
She said the incident was so embarrassing she could now "never go back".
