The photos may be cute but the response from his followers and friends was even cuter.
"So cute I can't," wrote Lee's new wife, Georgia Love, whom he met on the dating reality show.
"ADORBS!" exclaimed Studio 10's Sarah Harris.
"Geeeeez he was a handsome kid," noted Lee's friend and former Bachelorette co-star Cam Cranley.
TV and radio presenter Shura Taft even indulged Lee's love of puns and commented: "Eye am all four this."
2021 has already been a big year for Lee.
Not only did he and Georgia tie the knot in March but just weeks later, Lee also celebrated his milestone 40th birthday with his new wife and their close friends and family.
In fact, Lee's custom-made cake featured a young, adorkable Lee during his school days on one side and one of the shirtless handsome man he is today on the other.
Lee and Georgia, who met and fell in love in 2016 whilst filming The Bachelorette, tied the knot at the stunning Frogmore Creek Winery in Tasmania.
The couple originally planned to wed in Italy but, due to the coronavirus, they were forced to cancel and reschedule.
Nevertheless, the newlyweds have been delighting fans with photos and videos from their special day, with Georgia recently sharing a clip from the fun-filled reception.
"It’s been a minute. Time to revisit this night for the 578th time. Will we ever get over it? Absolutely bloody not," she captioned the Instagram video.
