One asked, "I thought it was an engagement shot but your finger was out of view!" with another adding, "Damn it, I thought it was an engagement post again! Come, on; Andy!!"
This fan summed up many commentors thoughts, writing, "Thought you were engaged! Just two beauties 💖"
Lee, 36, and Harding, 26, have been together for 21-months and dated for 18-months in the past before they had a short split.
Back in May, the radio host told the Kyle and Jackie O show that he and Harding were not engaged, while he recently shared to KIIS 101.1's Jase and PJ, that there is just one thing stopping him from getting on bended knee.
"I have a funny thing with Bec. Bec has never told me her ENTER score, what she got when she finished year 12. Never told me or told anyone," Hamish Blake's partner said, adding, "I said to her, 'If you want to be proposed to, we can't have any secrets. So the day you tell me your ENTER score is the day I know you're ready'."
