According to the source, there were "several occasions" where contestants passed out during the rose ceremony and the women were "clearly drained" by the hectic filming schedule.
"The contestants would be berated if they weren't enthusiastic about filming a scene and would have to re-shoot it many times until it was 'perfect'. In one instance, the girls had finished filming a rose ceremony into the wee hours of the morning before being asked to film another scene immediately afterwards.
"They were told to put on their pyjamas and rub off their makeup and pretend it was a new episode. The girls were clearly drained during this scene, but producers told them that they weren't be allowed to go to bed until they lifted their energy."
In response to the claims, a Warner Bros spokesperson told the Daily Mail: "The rose ceremonies last longer than the few minutes that are seen on television and participants are advised of this.
"Warner Bros. take the duty of care of participants very seriously and are advised to inform staff if they are not feeling well at any time. Certified first aid crew are on hand at all times to attend to anyone who should require it.
"Catered food and non-alcoholic beverages are available to the Bachelorettes before, during and after cocktail parties. If they feel like something else, their kitchen is full of good food that they have access to."
