The singer was a guest on the UTV daytime show and was promoting her latest single when she crumpled to the floor, with her backing band rushing round and coming to her aid.
She told fans on Wednesday that she was feeling unwell and suffering from a "bug", but was hoping to be well for her day of promotion.
Fans expressed their concern, with many posting messages on Twitter asking about her welfare.
Following the incident Ferguson took to the social networking site to reassure fans she was fine.
She wrote: "I am feeling much better will rest today so sorry to worry everybody I fought through that song but at the end had nothing left love yas xxx."
A spokeswoman for the show said: "Rebecca became unwell during her performance on the show today. She was seen by a nurse at the studios and is fine now."
