As she shared on Instagram, "endlessly in love with the year I've had! grateful for my friends, family, donkey (bernard), my doggies, my puppies teeth, and my partner for life."
Alongside a carousel of photos, including some silly snaps with Jon Bon Jovi's son, Millie continued, "here's to another year with you and the wonderful people and animals around us," adding, "let's do it again but better!"
One black-and-white photo featured Millie, 18, and Jake, 20, sharing a kiss in a photo booth, while another pic showed them leaning toward each other in the car.
Under the post, Jake wrote back to her, "Your year babe love you so much." He too shared some precious photos of the couple in honor of the New Year, captioning his, "Love is all you need."
