"I love u baby, happy anniversary," the Young and the Restless actor wrote on Instagram, alongside a photo of them both. For the couple's special outing, it appeared the singer had love on the brain. Demi donned a flirty fuchsia dress that featured puffed sleeves and a mod-style silhouette. She accessorised with heart-shaped drop earrings and a black-and-white handbag that was also shaped like a heart. Max also dressed up and rocked a black graphic tee and paint-splashed jeans. Max and Demi recently enjoyed some alone time at the Malibu restaurant. "Date night at Nobu," the singer wrote on Instagram, alongside a cute photo, "I love you." Just last month, the couple announced their engagement on social media.
