Sharon Osbourne on Kelly's Seizure Scare

Sharon Osbourne took to The Talk Monday to give an update on her daughter Kelly Osbourne's health, after the Fashion Police co-host suffered a seizure while taping the E! show Thursday and was immediately rushed to the hospital.

"Kelly is doing fine," Sharon smiled, clearly upbeat. "First off, Kelly has asked me to thank everyone for sending their love to her and [those who] have reached out to her ... We all believe in the power of positive thinking and sending good vibes. We strongly believe in it in the Osbournes."

She also revealed that Kelly will be released from Cedars Sinai Medical Center in Los Angeles today, where's she's been staying for observation.

"After the show I'm going to pick her up and give her a good smack," she joked.

However, doctors are still unsure what caused the seizure in the first place.

"We are blessed in a way that when Kelly had her seizure, she had it while she was filming ... we needed that to show the neurologist so they could see what was happening," she explained. "And she's on medication, she's fine. Nobody knows why she had it -- can't figure out a reason why, but she is fine and naughty. Very naughty."
