Taylor Swift is making a splash in the pop world with “I Knew You Were Trouble,” which logs its third-consecutive week at number-one on Billboard’s Top 40 chart this week. Internationally, “Trouble” has hit number-one in five countries, and it’s a top 10 hit in countries across four continents.

A six-time Grammy winner, T scored the coveted opening number at the Grammys on Sunday. She’s up for three awards, including Record Of The Year for "We Are Never Ever Getting Back Together." Due to high demand, she continues to add new shows to the Red tour, which kicks off next month in Omaha, Nebraska.
