Throwback Thursday is the perfect time to reminisce about life's happiest moments.

The team over at LaurenConrad.com posted a #tbt photo from Lauren Conrad and William Tell's September wedding, taken by photographer Elizabeth Messina. The snapshot shows the Paper Crown designer, dressed in her stunning Badgley Mischka Couture gown, walking arm-in-arm with her new husband, both smiling brightly:

On New Year's Eve, the 28-year-old shared a sweet photo from the nuptials on her own Instagram account:

Conrad and Tell married four months ago in a ceremony in Santa Ynez, California. In October, Conrad's longtime best friend and one of nine bridesmaids, Lo Bosworth, dished about the big day while chatting with HuffPost Live.

"She was one of the most dazzling brides I've ever seen. The gown was so spectacular, [and] she was a very, very calm bride," Bosworth said. And the reception was pretty great, too. "Good cocktails. Good bartenders. My friends and I, we know how to have a good party."
