Mel B was rushed to the hospital after losing vision in her right eye.
The mother-of-three stopped seeing properly on Friday, just weeks before the Spice Girls reunion tour is due to kick off.
According to The Sun, she arrived at Moorfields Eye Hospital in London and told medics that she was “totally blind” and “couldn’t see anything.”
The 43-year-old cannot see with her left eye due to a botched laser surgery done 20 years ago to correct her vision but which ended up going wrong.
A source to The Sun: “Mel was in a really bad way. The other girls and their managers were really worried.
“Mel was frantic and screaming that she couldn’t see a thing. She went to the hospital in a chauffeur-driven car with an assistant, who was holding her hand. No one knew what brought it on but she had very swift, and very good, treatment.”
After arriving at the hospital, Mel B was later transferred to Luton and Dunstable Hospital’s ophthalmology department and was discharged when she was able to see again.
A spokeswoman for Mel B said: “The situation with Mel is under control. She is looking forward to the tour.”
