Lorraine Kelly has returned to present her ITV show this morning (September 2) after taking a short break throughout the summer.

It comes as the 64-year-old announced the arrival of her first grandchild over the weekend, saying “she’s been welcomed into the world with so much love”.

Lorraine has one daughter, podcaster Rosie Kelly Smith, with her husband Steve Smith.

Rosie announced her engagement to fiance Steve White in June, two months after revealing she was pregnant.

Lorraine Kelly says she is 'so proud' of her daughter Rosie

In an Instagram post on Sunday (September 1), Kelly wrote: “I have been bursting to share this wonderful news with you! Baby Billie is an angel and I’m so proud of @rosiekellysmith and @stevewhite94 who will be the best parents.

“I’m delighted to be Granny Smith and can’t wait to go on adventures. #love #joy #happiness #family.”

Billie Kelly Smith-White was born on Thursday, she added.

Kelly also wrote: “It feels like she’s been here the whole time and we’re not quite sure what the point of anything was before.

“I’d heard how amazing midwives are but they are genuinely walking angels – she’s been welcomed into the world with so much love already.”

Sharing photos of the baby grabbing hold of a finger, Kelly was congratulated by Ranvir Singh, who fills in on Lorraine, as well as former Countdown star Carol Vorderman and ITV Good Morning Britain presenter Kate Garraway.

Singh wrote: “Awww the happiest days yet!!! So delighted for you all.”

Vorderman commented: “How wonderful. Little Rosie… I remember her at nursery school Lorraine.
