Gabby Thomas has more bling than just her Olympic gold medals ... the track star is engaged after her man got down on one knee and popped the question -- and the rock is massive!
Gabby and her fiancée Spencer McManes announced the amazing news on Tuesday ... revealing he proposed during a staycation in Texas.
McManes -- founder of drink brand Kaviva -- picked a romantic spot ... the rooftop of an Airbnb where they were staying. Gabby's best friend, as well as a photographer, were waiting to capture the special moment.
Thomas was totally shocked ... "Normally he’s very bad with surprises, and this was the one surprise I think I've ever witnessed him keep."
The couple first connected in 2021 through social media after a mutual friend suggested they'd make a cute couple. Once Thomas followed him on Instagram, he DM'd her.
"I got the notification that I had a new follower," McManes said, "I was like, 'That's crazy! Gabby Thomas?'"
"I immediately DM'd her and asked, 'What did I do to earn a follow?'"
Well, their friend was right ... the two started dating the following year, and now they're about to plan a wedding!
FYI, Thomas -- who secured three gold medals in the 2024 Olympics -- isn't the only athlete in this relationship. McManes played for the Yale football team from 2013 to 2016. He also played for Austin Huns Rugby Club.
Congrats!
