Sharing a photo of Chris tending to her - Liv clearly had a few issues with the 40-year-old.
She jokingly penned, "Me repeatedly over the last 24 hours: 'You're an animal doctor. I'm a human.'"
Despite all the photos together, the couple have never formally acknowledged her romance.
She told The Daily Telegraph in February, "No, I'm not married."
Meanwhile, Chris told Stellar magazine earlier this year, "I am looking for The One. I don't want to be this person with a history of short to medium length relationships."
"I've probably prioritised work more than I potentially should have over the past 10 years – to the detriment of my personal life."
