The professional dancers got married at Bella Blanca in Los Angeles, CA, on Sunday, Us Weekly reported.
"As Emma walked down the aisle, instantly locking eyes with Sasha, it was as if time stood still," wedding planner Michael Russo told Us.
"Their moving vows had moments of both humor and heartfelt emotion, which made the ceremony a truly special and magical thing to behold. I couldn't be more proud to have been a witness to this celebration of pure, unconditional love."
The bride, 29, reportedly donned two beautiful Rivini gowns for her wedding day and held onto a bouquet of fresh pink flowers.
Emma and Sasha reportedly chose to do "first look" photos at Houdini Estate, which is a location that has special meaning to the lovebirds given they pass by it almost every day while walking their beloved dog, Ruby.
When Emma walked down the aisle for the ceremony, she wore a sleek, fitted and sheer dress with lace appliques, and for the reception, Emma danced in a whimsical, less-traditional dress with a long flowy skirt, according to Us.
And the groom, 33, sported a handmade tuxedo by Onik Design, the designer behind many Dancing with the Stars ensembles and costumes, according to Us.
The family-style menu reportedly featured a wide range of options for the palate, as the guests feasted on smoked salmon, red caviar, seared ahi tuna, pork belly, ribeye steak, lamb, avocado salad and charcuterie, and more.
Emma and Sasha also designed a cake with five layers of flavor: Valrhona chocolate, vanilla bean, carrot, almond, and banana layers.
The pro dancers shared their first dance as husband and wife to "Perfect" by Ed Sheeran, who reportedly recorded a sweet message for the couple that played before they took the floor.

The wedding favors consisted of scented candle and tequila, according to Us, while the bridal party received fuchsia clutch handbags for the bridesmaids and tan leather wallets for the groomsmen.
Emma and Sasha dated on and off from 2011 to 2015, and in December 2015, Sasha confirmed he was back on with the blonde beauty.
