Taylor's 'Mine' took the biggest award for Video of the Year - ¬ the third time she has won the category in four years - while Justin and Rascal's 'That Should Be Me' was named Collaborative Video of the Year.
Taylor couldn't attend the event, as she is on tour, but received her award via live video link up, saying: "I wish I could be there, but I'm hanging out with 15,000 of my closest friends in Milwaukee," as thousands of fans cheered in the background.
Blake Shelton was the only artist to win two awards: Best Male Video for 'Who Are You When I'm Not Looking' and Best Web Video for 'Kiss My Country Ass', while his new wife, Miranda Lambert also triumphed, winning Female Video Of The Year for 'The House That Built Me'.
She later presented an award with SARA EVANS, who joked: "Well, at least you were wearing underwear!"
To which Sheryl replied: "I was wearing underwear because I'm good, clean, wholesome family fun."
