BBC Radio 1 star announces her pregnancy live on air and leaves her co-stars stunned with surprise baby news

A BBC Radio 1 star has revealed her pregnancy live on air.

Katie Thistleton left her co-stars Mollie King and Matt Edmondson stunned on Wednesday as she told how she was expecting her first child with her husband Alex.

The 35-year-old announced her happy news while hosting a quiz for her colleagues, with Mollie and Matt left screaming from the surprise.

She said: 'I've got a question for you guys and that is: What is the last message that you were sent on WhatsApp. So if you could all open your WhatsApps, please.'

As the pair then expressed their shock and squealed loudly, Katie explained: 'I’ve just sent Matt and Mollie a scan photo and a message saying me and Alex are having a baby.

'I was so scared that that would go wrong, like the WiFi wouldn’t send it.' 

The Saturdays star Mollie, who is expecting her second child with fiancé Stuart Broad, was particularly excited by the news, with Katie revealing she'd been wanting to spill the beans to her fellow mum-to-be.

She shared: 'I mean, oh my god Mollie I’ve wanted to talk to you about this so much. 

'There was a day when you walked past us and I was like, "how are you2 and you were like, "I’ve been so sick" and I was thinking, "me too I’m so sick but I can’t tell anyone yet". But yeah, I’m due in March so not that far behind you really.'

After the sweet radio announcement, Katie took to Instagram to confirm her happy news with a sweet video montage.

'We’ve been married 3 gorgeous years today, feels like a good time to announce the next chapter. Watch for a surprise.'

The images and clips in the montage featured Katie and Alex's engagement and wedding, as well as the couple holding up their scan photo.

Other cute moments include the couple embracing as they count down to parenthood as well as Katie showing off her growing bump. 

Katie joined BBC Radio 1 in 2017 and currently co-hosts Radio 1's Going Home with Vick, Katie and Jamie, alongside Vick Hope and Jamie Laing.

She initially hosted Radio 1's The Surgery alongside Radha Modgil before going on to present Life Hacks and The Official Chart: First Look alongside Vick until 2024.

After regularly acting as a stand-in on Going Home with Vick and Jordan, she was made a permanent host earlier this year following Jordan North's departure.   

The presenter's live announcement was also shared on Radio 1's Instagram page, alongside the simple message 'Congratulations @katiethistleton!!'

The post garnered plenty of congratulatory messages from Katie's fans and fellow TV and radio stars.

After recovering from her shock, Molly King wrote: 'Absolutely THRILLED for you gorgeous girl!!!! You’re going to be an AMAZING mum!!! Love you so much! Thank you for sharing this news with us.' 

Chris Stark penned: 'Awww incredible news. Big love Katie and Alex. I hope they are better behaved for you both than me at a maccies drive through x.'

Melvin Odoom shared: 'Amazing reveal congratulations.'

Charlie Hedges wrote: 'The BIGGEST congratulations again to you both. The most beautiful beautiful news xxxxxxxxxxx.'
