Julianne Hough's hard work is paying off. On Wednesday, the actress put her enviable abs on display in a crop top after hitting the gym in LA. In addition to baring her midriff, Julianne nearly blinded photographers with her massive engagement ring, given to her by fiancé Brooks Laich [1]. This is just the latest we've seen of the star since she attended a fundraiser in Santa Monica, CA, earlier this month, though we did catch her hanging out BFF Nina Dobrev [2] at a charity event that same week, adding to their lengthy list of cute moments together [3]. Read on to see more of Julianne, then get a load of her bangin' bikini bod [4].
