What did you miss?
The reality TV queen, 71, has shed 42 pounds since she started taking Ozempic last December, a drug designed to help Type-2 diabetics manage their blood sugar levels.
Speaking to Kate Garraway and Ben Shephard, Osbourne also discussed moving to the UK from sunny Los Angeles and the special name her grandchildren have given her as well as the "five year of nightmares" they have faced over her husband's health.
What, how and why?
Osbourne shared her husband's response to her sudden weight loss after taking Ozempic.
She said: "Ozzy doesn’t like it. He’s scared. He thinks something’s going to happen to me. There’s nothing perfect. He’s always thinking of the downside, ‘too good to be true’."
Her weight loss has courted a lot of attention and the TV personality confessed she could do with "putting on a few pounds".
She added: "At this point my body is not listening it’s staying where it is."
Osbourne said she had decided to try the drug because she was "fed up" with yoyo-ing with her weight.
"Iwas just fed up going back and forth with my weight," she explained. "I just thought I’ve tried everything. I’ve tried everything. Might as well try it!"
However, she expressed her "only fear" was for young teenage girls who might try to get their hands on Ozempic.
"It does what it says on the packet, it absolutely does," she said. "My only fear, it’s put in the right hands. I don't think it’s for teenagers. I’m scared for 16-20 year olds.
"I can eat what I want and keep taking this injection. I think it needs to be in the hands of older people that totally understand that there could be side effects to this."
She added: The world we live in today everybody wants to be skinny."
What else happened on Good Morning Britain?
Osbourne detailed the "nightmare" of her husband's health battles and the impact it has had on them, including his Parkinson’s diagnosis and surgeries after his severe falls.
She said: "Nightmare. It has been five years of nightmares. Operations. Just I do not know how he has stood for it."
But his health has taken a change for the better. She revealed: "He's good. No more operations, they're all done. He's looking forward to coming back to the UK."
While Ozzy is excited about the UK move, she also shared: "He's the one who has been here the least. He's excited but he's a bit scared no one will know him anymore!"
Personally, she has been very excited about the move. "I'm not very American, some people can go there and adapt their persona and you become the country you live in," she said.
"Yesterday was Thanksgiving, years and years we've been there and I've not been celebrating Thanksgiving. I've never became a full part of it."
It's a different story for the kids as Osbourne admitted especially Jack has become very American. "He has four American babies," she said.
As talk turned to babies in a heartwarming moment on Good Morning Britain and Osbourne shared her grandchildren's sweet names for her and Ozzy.
The famous couple have five grandchildren: Kelly's daughter Sidney as well as Jack's children Pearl, 10, Andy Rose, seven, Minnie, five, and Maple, one.
"I love it, love it, love it," she said of being a grandmother to five. "You get a second chance to hold those babies."
The TV star revealed they call her "nanna" and Ozzy is "pappa" to them.
Of course the famous couple also have a movie being made about them. Osbourne would love to see an unknown actor play her husband.
