The power couple, who often dish out goals on social media, have time and again sent out hearts aflutter with their PDA and with Valentine's Day in the US today, looks like Nick is also on cloud nine. Wishing his forever valentine, the Jonas Brothers singer shared monochrome pictures with the love of his life and wrote, "My Valentine," with a heart emoji.
