BELFAST — Lady Gaga’s global domination is showing no signs of slowing down, with the singer winning four trophies at the MTV Europe Music Awards, including best song and top video (both for “Born This Way,”) as well as best female performer.Gaga also wowed the 8,000-strong crowd at the ceremony in Belfast’s Odyssey Arena with her performance of “Marry the Night.” Underlining America’s vise-like grip on pop, the Euro MTV awards also saw Justin Bieber picking up kudos for pop and male performer, while Thirty Seconds to Mars took the alternative and world stage prizes. Bruno Mars also won two awards, including new artist. But the night was all about Gaga, with show host Selena Gomez mimicking her famously outrageous fashion sense throughout the night. Gomez simultaneously hosted the main show and the digital show, as well as singing her hit “Hit the Lights.” Joining Gomez onstage were Bieber, David Guetta, Mars, Coldplay, Red Hot Chili Peppers, Jessie J, LMFAO, Snow Patrol and Queen, who closed the show, having accepted the Global Icon award from Katy Perry, who took the live performance award. “American Idol” star Adam Lambert fronted the band. Other winners were Eminem (hip-hop), Linkin Park (rock) and Bigbang (worldwide).
