Mel B's estranged mother has pleaded for information about her daughter on Twitter.

Andrea tweeted: "Mothers worse nightmare to hear ur daughters seriously Ill in hosp and not know where to go!! (sic)."

Mel's sister, Danielle, aired her frustration and upset as she took to the social media website to brand the whole thing "cruel".

She wrote: "It's just horrific!!!!!!

"This is ridiculous and cruel !!! Evil ! How can NO one tell me and my family where my sister is and what is going on?????

"Just a simple call to say she gonna be ok is all it takes!!!! (sic)"

Danielle - who fell out with her estranged sister after a public feud

- admitted that she was "desperate" for any updates.

She tweeted: "I am beyond desperate and this should be a private family matter!!

"But we don't know what else to do if anyone at all can help then pls do! (sic)"

The actress also slammed Mel's husband, Stephen Belafonte, branding him an "evil liar".

She wrote: "STOP @stephenthinks1 with your evil lies!! You told me and my mum yesterday she is fine and not in hospital @SimonCowell just doing press! (sic)"

Meanwhile, the 'The X Factor' judge - who missed the first part of the talent show's final on Saturday night - reportedly owes her life to her chauffeur, who drove her to hospital after she collapsed in his car.

The insider shared: "Mel seemed OK when she first got into the car - but during the journey it gradually became clear something was very wrong.

"She was complaining about stomach pains that seemed to grow worse and worse, until she was in agony. She was crying out.

"Mel was in so much pain that the driver rushed her straight to hospital. It was a terrifying episode - he had no idea if Mel was going to be OK or not."
