Happy National Proposal Day! See Celebrity Engagement Rings

Love is in the air today, can you feel it? It's National Proposal Day!

Inspired by the holiday, we’re taking a look at Hollywood’s hottest couples who put a ring on it recently, including Drew Barrymore and art consultant boyfriend Will Kopelman, Justin Timberlake and Jessica Biel, and Halle Berry and Olivier Martinez. See our favorite engaged celebrity couples—and their stunning sparklers—in the gallery.
