Gwen Stefani was over the moon when she discovered her Valentine's Day gift from Blake Shelton on Wednesday (2/14). In a video posted on her Instagram Stories, Gwen can be seen walking into a room and finding an extra-large floral arrangement sitting on the table. As she discovered the floral arrangement made up of dozens of red roses and pink orchids, Stefani exclaimed that she'd never seen anything like it and wrote that she was the "luckiest girl in the world."
