The former 'X Factor' star had just finished singing her new single 'All That I've Got' when viewers saw her step away from the microphone holding her chest before she doubled up and began to collapse.
The daytime show then cut to the closing credits.
But the 27-year-old singer has since taken to Twitter to assure fans she will be taking it easy for the rest of the day, blaming her collapse on her having 'nothing left' to give following her performance.
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— Rebecca Ferguson (@RebeccaFMusic) February 27, 2014
Shocked fans have also taken to Twitter to wish her well...
