Kristen Bell and longtime sweetheart Dax Shepard attended Sunday night’s Grammy Awards, with Bell resplendent on the red carpet in Jimmy Choo shoes and a dress by Etro, but the highlight of the outfit was Bell’s new engagement ring.

Designed by Neil Lane, it is a cafe au lait-colored, emerald cut diamond approximately the size of a headlight on a 1987 Jeep Wrangler. Set in platinum, the rock is surrounded with smaller accent diamonds. Bell was photographed looking triumphant next to her squeeze Sunday night, and confirmed the news that she and 35-year-old Shepard will wed after having been together for many years.

Bell, 29, stars in the television show “Heroes,” while Shepard has been on “My Name is Earl” and “Punk’d”

The two recently starred in the romantic comedy When in Rome. In the movie, an ambitious New Yorker, played by Bell, scoops up some magic coins from a fountain that make a bunch of dudes fall in love with her: a sausage mogul, a street magician, a painter, and a self-absorbed male model, played by Shepard. The movie has been variously reviewed as “annoying,” “painfully bad,” and “pointless.”

Here’s hoping the couple’s off-screen life will be otherwise.
