Others mirrored the statement and commented: "Are you feeling well yet?" and, "please get well soon," and there were strings of heart emojis and pleas for new music too.
Celine – who was forced to postpone her Las Vegas residency in October due to her health – revealed over the holidays that she is still not well enough to perform and she had to cancel the remaining shows of the North America leg of her Courage World Tour.
In a heartfelt message, Celine wrote: "I was really hoping that I'd be good to go by now, but I suppose I just have to be more patient and follow the regimen that my doctors are prescribing.
