The former Atomic Kitten singer took to Twitter.com to tell followers her partner is currently undergoing a battery of tests in hospital, writing, "Asking you all to say a prayer for my (husband, he has) been taken into hospital with signs of a stroke."

Kay, 35, was well enough to write his own update on the microblogging site, adding, "Hoping it's bells paisley (think that's how you spell it)".

Bell's Palsy is a condition which causes temporary weakness or paralysis of the muscles in one side of the face, a similar symptom to that of a stroke.

Katona and her third husband Kay have been married since September (14).
