Olivia Newton John's daughter Chloe Lattanzi is by far the greatest joy in her life.
And in now a new interview with Page Six, the Aussie superstar has revealed that grand-babies are certainly on the cards.
"I would love that, but yeah I have 'grandogs' right now," Olivia, 70, told the outlet.
"They're talking about it, but they've been talking about it for a long time," she revealed of her daughter Chloe and her fiancé James Driskill.
"So I don't know when that will happen."
Back in December, Chloe wrote an article for Woman's Day paying tribute to her mum.
''To most people she is Olivia Newton-John, the star, but to me she is simply my mum and I couldn't be more thankful for that. When I think back to my childhood, it's full of magical memories she helped create," Chloe wrote.
Chloe recalled that she was "just five" when she realised her mum was famous, after "thousands of people" were jumping over their car "screaming her name".
But to her, Olivia is just her mum and she knows that when she has kids, she will be a fabulous grandma.
"Having a baby has been on my mind a lot lately, and when I'm ready I know Mum will be the best support system," Olivia said in her letter.
"We've been through a lot together, but not a day goes by when I'm not happy and proud to call her my mum."

In 2018, after two battles with breast cancer starting in 1992, Olivia confirmed that she was battling cancer for a third time.
In November last year, the former Grease star decided to auction off her wardrobe from the iconic film to raise money for the Olivia Newton-John Cancer Wellness and Research centre in Melbourne.
"I don't feel I'm parting with them," she told Page Six Style at the time.
"I have a photograph of them, which is probably better than having it in the closet, and I feel like I've had my time with them. I'm happy that it's going to go to people that will enjoy it."
In June this year, she also auctioned off the leather jacket and skin-tights Sandy wore in the final scene of the cult classic - which reportedly went for approximately $US200,00 (AUD $290,000).
Other Grease memorabilia up for grabs included Olivia's original script from the film, a Grease 10-times platinum award and her "Pink Ladies" custom jacket plus.
