Upton’s rep confirmed the engagement to ET. The 33-year-old baseball player popped the question more than two months ago, with the couple keeping their upcoming nuptials on the down low -- they haven’t even set a date yet!

But the cat’s officially out of the bag! Running her fingers through her hair, Upton flaunted her the gorgeous ring while talking to ET on the Met Gala red carpet, wearing a Topshop gown.

“I got my dress inspiration from the new Batman v Superman,” she said. “Wonder Woman, because her accessories are powerful, and so I thought in today's world, technology is our accessory.”

Upton also braved a new do for the glitzy event.

“I cut my hair right before… a good amount,” she shared. “I had so much anxiety cutting my hair, but it grows back!”
