Sofia Vergara and Joe Manganiello might already be engaged and close to their wedding day, 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, 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 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, after Joe asked Sofia's costar Jesse Tyler Ferguson to play matchmaker.
