BBC Morning Live star Xand van Tulleken introduced his adorable newborn baby boy to his co-stars while live on air.

The TV presenter and doctor, full name Alexander van Tulleken, first shared the exciting news alongside his wife Dolly. Posting the announcement on the show's official Instagram account, a message read: "Congratulations to Dr. Xand and his wife Dolly on the birth of their baby boy, with arguably the best name ever, Rex Patrick Anthony van Hoogenhouck-Tulleken.

"The Morning Live family has become even bigger and we can’t wait to meet him!" On Friday morning, Xand officially introduced the adorable baby boy to his co-stars, who could be heard cooing over the little one - who was fast asleep when he appeared on the video call.

When asked how everything was, Xand said: "It is absolutely extraordinary. Dolly has been amazing. If anyone wants advice on how to be the best husband out there, my only tip is to get a good eight hours of sleep every night which is sort of what I've been doing. Dolly has been up feeding and figuring everything out.

BBC Morning Live cooed over the newest addition to the team

"I said, 'Why don't you wake me up?' and she said, 'I tried'." He went on to give a shout-out to the midwives and the staff at the hospital. He said Dolly mostly did a home birth but ended up in a 'bumpy ambulance ride' for the last moments and, thirty minutes later, he was born.

He added: "We're so lucky. We are in our bubble." Dr Xand married doctor Dolly Theis, who is a visiting researcher at MRC Epidemiology Unit, University of Cambridge and former Conservative Party candidate for Vauxhall. He has a son named Julian from a previous relationship.

After welcoming Rex, he and Dolly were flooded with congratulatory messages as Dragon's Den star Sara Davies said: "Amazing news!!!" Great British Bake Off's Briony May Williams added: "Such wonderful news Congratulations." TV chef Anna Haugh commented: "Such amazing news. Congratulations guys xxxx."

A fan shared: "Lovely news this morning! Congratulations to the new family xx." Strictly Come Dancing's Neil Jones added: "Amazing congratulations." Dr Xand is known for presenting the CBBC series Operation Ouch with his identical twin brother Chris. He has also presented Channel 4's How to Lose Weight Well.

The TV star has regularly offered up his own body for science experimentation on the diet show. He has hosted BBC Horizon episodes Sugar vs Fat as well as Is Binge Drinking Really That Bad? Dr. Xand started appearing regularly on BBC Morning Live in July last year where he offers a variety of medical advice. He also presents the Made of Stronger Stuff podcast on BBC Sounds.
