Susan on song.
The 48-year-old is scheduled to join rehearsals for the Britain's Got Talent tour in London at some point today.
Bosses hope this means that she will take to the stage for the first live show in Birmingham on Friday. A source said: "It is cutting it fine but Susan begins rehearsals on Thursday.
"There is no pressure on her at all but everyone is hoping this means she will now perform on Friday night."
Susan left the Priory Clinic in north London last week after being admitted for exhaustion following losing the TV talent show to dance act Diversity.
