Duchess made her first public appearance last night after being hospitalised for morning sickness.
She had cancelled several appearances following her recent illness and was released from King Edward VII Hospital in London on December 6 after being treated for Hyperemesis gravidarum.
The condition causes severe nausea and vomiting and can lead to dehydration and weight loss and typically does not ease until 17 to 18 weeks into term.
Braving cameras, she looked stunning as she presented awards at the BBC Sports Personality of the Year ceremony.
She wore an emerald green skirt suit and appeared "healthy and strong", according to the Associated Press.
She presented two awards at the London event: the Lifetime Achievement Award to Chairman of the British Olympic Association Sebastian Coe, and the Sports Personality of the Year award to Olympic cyclist Bradley Wiggins.
Meanwhile a former royal confidant has said Kate and Prince William won’t “spoil” their baby.
Princess Diana’s hairdresser and confidant Richard Dalton believes the royal couple will be keeping things low-key when the baby arrives.
“William was brought up to work hard and respect others, so I don’t envisage him or Kate allowing their child to be spoilt – far from it!” he assured British magazine new!
“I should think they’ll both be quite strict.”
The stylist personally attended to Diana’s hair and remembers how she was with her own children, William and Harry.
Richard shared a moment from William’s early life, demonstrating his firm but fair upbringing.
“When William was tiny, I’d turn up to do his mum’s hair and there he’d be running around the nursery,” he reminisced.
“Like any toddler, he’d push the boundaries and have a bit of a strop. One day, he was crying because he’d finished his ice cream and wanted some more but a ‘no’ was a ‘no’.”
Whereas the new arrival may not be spoilt by its parents, it seems outsiders are eager to offer the royal baby lavish gifts.
Recently TMZ reported the couple had received a host of presents for the baby, including a basket of luxury goodies worth $2,300.
