Sofia Vergara and Joe Manganiello might already be engaged and close to their wedding day [1], but it was only a year ago that they started dating. The couple celebrated their first anniversary with a cute PDA-filled snap on Sofia's Instagram feed [2], which she captioned, "Happy 1st anniversary, love of my life!!! Never been so happy!!" The Modern Family actress has been open about how she knew Joe was the one [3] she wanted to be with, saying, "I finally realized that relationships don't need to be so much work." The sexy couple started dating last year [4], after Joe asked Sofia's costar Jesse Tyler Ferguson to play matchmaker.
