Hunt and McDonald have a private relationship, only making very few appearances on one another's feed.
"Love you both so much," fellow VS star Gigi Hadid commented. Several other A-listers offered their congratulations to the couple in the comments as well, including fellow model Lily Aldridge and pal Cazzie David.
“!!!!!!!!💍!!!!!!!!!!!!” David wrote, to which Hunt replied, “@cazziedavid got a ring on it!!”
Queer Eye’s Antoni Porwoski joked, “WHAT IS IT?!? WHAT’S THE SECRET?!! DON’T LEAVE ME HANGING!!”
McDonald also shared the happy news with a pair of black and white photos shared on his own Instagram.
“💍 BEAR-er” he wrote.
Congratulations to the couple!
