GLASGOW presenter Lorraine Kelly has said she “cannot wait to be a granny” after her daughter announced she is pregnant.

Rosie Smith, 29, is the only daughter of the Gorbals-born TV presenter and husband Steve Smith.

She announced the news on Instagram with a picture showing her cradling a baby bump.

Another image of a framed sonogram picture revealed Smith was at least 12 weeks pregnant, with writing underneath saying: “The bean at 12 weeks – the size of a fig."

Alongside the post, Smith, a podcaster, wrote: “We could not be more excited – you’re already so loved little one.”

ITV host Kelly shared the post on her own Instagram account, writing: “The most exciting thing to have ever happened in our family!

“Cannot wait to be a granny and so proud of Rosie and her Steve.

“It’s the best news EVER!”

Smith’s partner Steve White posted a picture of their dog wearing a bandana which had “only child” crossed out to be replaced with “big sister”.

He joked that their mini wire-haired dachshund Ruby “might have some competition later this year”.

Kelly’s colleagues were among those to offer congratulations, including Good Morning Britain presenter Charlotte Hawkins who commented: “Oh my goodness what amazing news! So special."

Ria Hebden, entertainment presenter on Lorraine, wrote “congratulations Lorraine, wonderful blessings and you’ll be such a fabulous grandma” while RuPaul’s Drag Race judge Michelle Visage said “THRILLED FOR YOU ALL”.

The mother and daughter duo host a podcast called What If? where they discuss life’s defining turning points with celebrity guests.

Kelly has hosted her eponymous chat show Lorraine on ITV since 2010.
