Ever since Justin Timberlake popped the question to Jessica Biel this winter, the actress has been coy about showing off her engagement ring. For months, she didn't wear it to public events, and photographers only snapped a few shots while she was in transit. Well, no longer! The couple attended last night's Metropolitan Museum of Art’s annual Costume Institute Gala, where she posed arm-in-arm with her fiancé showing off her sparkler. Take a look at the custom piece, which features a large square-cut diamond in a vintage-inspired setting, in the photo above. Now that you see it close-up, what do you think? Leave your unfiltered thoughts in the comments!
