‘The sun baby’s baby!’ Fans rush to congratulate Teletubby legend as she welcomes first child

to share a snap of her newborn's tiny hand holding her finger, as she wrote: "One whole week of you".

Jess didn't indicate whether or not she'd had a boy or a girl, and also kept the name private too.

The baby is the first for Jess, who's in her mid-twenties, and her partner Ricky.

And in the comments section of the Instagram post, people were quick to congratulate the new mum.

"Yay. The sun babies baby! Congratulations," one wrote.

"Congratulations, 'Mrs. Sun'!" another added.

"Oooh. Congratulations," a third wrote.

"Good luck with being a mum. You can do it.

"You're gonna be a super mum.

"Enjoy the love and enjoy being together!"

"Proud of you," someone else commented.

"Welcome to the world,baby," another gushed.

Jess first gained huge success after appearing in the kids' classic TV programme The Teletubbies, where she greeted viewers as the giggling baby in the sun.

The show, documenting the goings-on of the cheeky creatures Tinky Winky, Dipsy, La-la and Po in Teletubbyland, ran between 1997 and 2001 - although it was rebooted around 2014.

Jess has previously shared to BBC South East about how she landed the golden gig, revealing it was down to a chance encounter.

“I was being weighed at the hospital,” she said.

“My mum took me and it just happened to be the same time that the producer of the old series had come in and wanted the hospital to get in contact with them if they’d seen any smiley babies.”

She revealed that while filming, her dad would sit behind the camera playing with toys to get her to do the now-iconic giggle.

Jess has been documenting her pregnancy on her Instagram page - sharing pictures of when she went to her scans, and from her baby shower.

"Cannot thank everyone enough for a lovely afternoon," Jess wrote alongside pictures of her "fantastic baby shower".

She also used the social media site to announce her pregnancy, as she shared pictures of the baby scan and wrote: "When two becomes three".

Ricky has yet to post about the new arrival on his own page.

However, he did share a snap earlier this month which showed him in what appeared to be the baby's nursery - with nappies and wipes in the background.

On a previous post where he joked he was "famous" because of his girlfriend's pregnancy, someone commented: "If it's a boy your son will be son of the sun!"
