The Big Bang Theory singer wed her tennis player beau Ryan Sweeting on New Year's Eve 2013, putting her own stamp on the ceremony by donning a candy floss pink gown.
And now Kaley has donned her gorgeous frock once more - and how fab does she look?!
Taking to Instagtam yesterday, actress Kaley posted a snap of herself rocking the stunning Vera Wang design, adding the caption: "I got to wear my wedding dress for a second time! I feel giddy! #weddingringermusicvideo @aloeblacc @verawanggang."
It seems Kaley donned her special attire while filming scenes for a new Aloe Blacc music video to promote her upcoming movie The Wedding Ringer, a comedy flick which is set for release next year.
And we can't say we blame her - with such a beautiful gown hanging in your wardrobe, it would be wrong not to whip it out now and then, right?!
Kaley and hubby Ryan married last year at Hummingbird Nest Ranch in Santa Susana, California, but they certainly didn't follow the rulebook with their wedding.
Not only did Kaley choose a sugary sweet pink frock over a traditional white gown, the couple also opted for an upside down wedding cake which dangled from the ceiling. Impressive!
The loved-up twosome announced their engagement in September 2013 after just three months of dating. They were introduced by a mutual friend with Kaley agreeing to go on a blind date with Ryan while he was visiting Los Angeles.
