"Yum 😋 Two cuties together and one of them looks very hot!" one fan exclaimed.
"You should have kids of your own and pass on those devilishly handsome genes!" penned another.
“I believe this is what the children call a 'thirst trap,'” model Simone Holtznagel joked.
"Seriously! I swear my ovaries just exploded," someone replied to Simone's comment.
Even Dr Chris himself weighed in, remarking: "This comment is getting a worrying amount of traction."
The TV vet has previously opened up about his plans to have his own family, telling Who that he'd "absolutely" love to have kids.
When asked what advice he would give his children, Chris said: "It’s probably to never underestimate the value of integrity. And try to avoid marrying a girl called Prue. Prue Brown is a name no-one should have to endure."
He also chatted to Stellar about how he'd want to be a hands-on parent.
"I certainly want to have kids and I don't want to be an absent dad. I know in my heart I'd want to be around for them."
Chris is currently dating 29-year-old model Brooke Meredith and previously dated Weekend Today executive producer Kendall Bora and The Loop's Liv Phyland.
Speaking to Stellar in 2019, the TV vet admitted that he had a wake-up call when he turned 40.
“It surprised me how much it got to me. It certainly made me look at where I am in my life," he told the publication.
"If you’d told me at 20 I’d be unmarried and without kids, I probably would’ve been horrified. But it’s my doing. I’ve probably prioritised work more than I potentially should have over the past 10 years — to the detriment of my personal life. I love my life, but it’s not without sacrifice.”
He added: “It’s a lot to ask of a girlfriend, to put up with all the travel and the lack of face time. There’s often interest in who I’m dating. I don’t want to put someone through that if it’s not going to be a thing.
“I’m certainly looking for the one. I don’t want to be this person with a history of short to medium-term relationships.”
