Hilary Duff and Mike Comrie basked in their newly engaged status over the weekend in Maui, where he popped the question on Thursday. Hilary flashed her gorgeous ring while at the airport yesterday, but before that it was all about romantic time with Mike. The two posed for photos with a photographer on their balcony and sipped red wine, and she even got playful kissing his stomach on the lounge chair. Hilary was clearly enamored with her diamond, an estimated $300,000, 4.5-carat sparkler, happily snapping pictures of it herself. Hilary and Mike fielded questions about tying the knot two and a half years ago when he bought her a car after a few months of dating, though she herself said she didn't want to rush into marriage. The timing seems especially sweet since Hilary's serious boyfriend prior to Mike, Joel Madden, just announced his engagement to Nicole Richie last week — wonder if the exes exchanged any well wishes. Congrats to the happy couple who waited until they were ready, and we're excited to see another celebrity bride-to-be!
