Wannabe pop star Abi Alton stumbled down a flight of stairs after being voted through to the next round of the talent show. She was stretchered out of the studios in London and taken to a nearby hospital.
She was checked over by doctors before eventually being released in the early hours of Monday morning (21Oct13).
Taking to Twitter.com, Alton writes, "out of hospital and thankfully there is no serious damage. Thanks for your lovely messages, im sure (I) will be right as rain in no time."
The 19 year old was the second hopeful to be hospitalised this weekend (19-20Oct13) - pregnant SeSe Foster, a member of Gary Barlow's group Miss Dynamix, was rushed to a medical facility after falling ill hours before Saturday's show (19Oct13).
Katy Perry and Robin Thicke both performed on Sunday's episode in front of judges Scherzinger, Sharon Osbourne, Take That star Barlow and music manager Louis Walsh.
