Ashley Tisdale Shows Off Her Giant Diamond Engagement Ring

Ashley Tisdale showed off her massive engagement ring during a walk with fiance Christopher French on Tuesday, and no wonder she's so giddy! Not only is the rock huge and sparkly and gorgeous, but her fiance is pretty fine too!

Last Thursday Christopher proposed to the former High School Musical hottie at the top of the Empire State Building in New York City, and on Monday she tweeted, "Thank you guys for all your well wishes. Means so much to me. We're so grateful and excited. #imthehappiestgirlintheworld."

We're excited for them ... such a cute couple!
