Back in 2018, Lisa and her ex-husband Grant Kenny teamed up with new parents Morgan and Ryan to introduce their first son Flynn to the world.
"I cried because it was like our baby's having a baby," the former Olympic and Commonwealth Games legend told Woman's Day at the time.
“I woke up in the morning to 100 missed calls, and all of a sudden I was a grandma. I cried, of course, he was just so adorable and content, and Morgan was so content. He had his eyes open when he was eight hours old, and was looking around at us with such interest. He's beautiful."
The lovefest for her first grandchild didn’t stop there, with Lisa again gushing about little Flynn to Now to Love in 2019.
"Flynn is just the most adorable child, he's just amazing," Lisa said at the time.
"He's crawling now, I don't think it'll be too long before he's taking his first steps. He's pulling himself up on the furniture and then lets go and stands there for about three seconds and then pops down onto his bottom but he's just divine.
“And the best thing about being a grandparent is you're able to have so much fun with them and then give them back!" she laughed.
She continued, "We all spoil him. Morgan was dancing in a big show on New Year's Eve in Singapore and Dad had to go back to work so Mark and I got to babysit Flynn for a day and night, half a day, and it was so much fun, it was really good."
When Morgan announced she was expecting her second child, proud mother Lisa again took to social media to confirm the news.
"YES!! I'm going to be a Granny again," the I'm A Celeb star captioned a sweet snap of her grandson Flynn.
"Getting ready to be a big brother," she added.
The star then gave a shout out to her daughter, writing: "Congratulations Morgan and Ryan. I can't wait for your little family to grow."

Upon Taj’s arrival in November 2020, Lisa once again took to social media to celebrate the new bundle of joy.
"IT'S A BOY💙💙💙💙💙💙Taj Grant Gruell arrived safely into this world last Thursday, 5th November 2020, 8lb 4oz (for the oldies like me who can relate better to pounds!!)," she joked on Instagram when the little one was born.
"A beautiful second son for my Morgan and Ryan and little bro for Flynn.... baby spam coming. Congratulations Morgan, Ryan and Flynn xxxxxx."
Among the collection of sweet snaps was a photo of a newborn Taj snuggling up to his doting grandmother, who smiles sweetly for the camera.
And it seems that young Taj is already taking after his Olympian nan, with Lisa sharing an adorable clip of Morgan and Taj in the pool during a swimming lesson in October 2021.
"And a little wave to Grannie during swim class 🥰," Lisa sweetly captioned the video in which Taj gleefully recognises Lisa filming from the sidelines.
"Swimming lessons for babies are so important so get them in the water as soon as you can 💙."
Lisa's doting grandma opportunities multiplied in May 2022 when Morgan and Ryan welcomed their third child, Kit.
The proud mum announced the safe arrival of her new bub via Instagram on May 24th, sharing a series of photos of the newborn as he settled into his family.
"Just like that…We are a family of 5!" Morgan penned. "On the 23rd of May at 3:30am we were gifted with another beautiful baby boy!! We are so in love with this little man it’s insane and watching Flynn and Taj cuddle and kiss him makes us so happy. We are meant to be parents of sons!
"Welcome to the family Kit James Gruell 💙."
Lisa was quick to congratulate her daughter in the comments section, writing: "Morgan my beautiful 😍… look at your gorgeous little family. I love you all so much and Jaimi would so love this too xxxxx 💙💙💙 Kit James xx."
