Happy Birthday, Diana! From lighting up the halls of West Beverly High on "90210" to stealing scenes effortlessly, you've always had a knack for making drama look fabulous. Seriously—how do you manage to age backwards while keeping your comedic timing so perfectly intact?Here's wishing you another year filled with laughter, applause, and roles as memorable as your iconic moments onscreen. May this birthday be even more glamorous than an episode finale—and may all paparazzi shots capture only your best angles (though let's face it—you don't have any bad ones!). Cheers to many more timeless adventures ahead!
