Victoria Fritz was reading the business news on BBC Breakfast in the UK on Tuesday morning when she went into labour.

The newsreader — dubbed Britain’s all-time sexiest presenter — was then rushed to hospital in Manchester, The Sun reports.

But fellow newsreader Sally Nugent, 45, had to step in as her birthing partner after Ms Fritz’s husband Dan got stuck in traffic.

Ms Fritz gave birth to a baby boy, who is yet to be named, at St Mary’s Hospital.

The new mum tweeted that the delivery was a “BBC Breakfast team effort”.

“My heartfelt thanks to @sallynugent & St Mary’s drs&midwives who helped me deliver my little boy yesterday. A @BBCBreakfast team effort!” she tweeted.

Sally Nugent replied: “It’s going to make a brilliant story for his 21st birthday! What an incredible day xx.”

Ms Fritz, who talked about easyJet’s latest figures on Tuesday’s show, married her husband in July last year in a stunning ceremony in Tuscany.

Speaking on BBC Breakfast this morning, newsreader Naga Munchetty explained why another presenter, Sean Farrington, was reading the business news.

She joked that Ms Fritz had “decided to be even more productive than she is in the workplace.”

“There she was, you know, just presenting very happily, not an issue in the world. And then she decided to have a bit of an event later on,” she said.

Co-presenter Dan Walker added: “Sally was reading our sport yesterday. Because Victoria’s partner was stuck on the M6, Sally was the birthing partner.”

He also tweeted: “If you’re wondering why @seanfarrington is a late sub today ... huge CONGRATULATIONS to @VFritzNews #ItsABoy.”

Dan Walker again tweeted: “Thank you for all your suggestions for baby names but I think Baby McBabyFace might not make the grade @BBCBreakfast.”

Ms Fritz has worked for the BBC since 2008, joining from financial commentary site “breakingviews” that is now part of Reuters.
