Lady Gaga hit the stage at the Oxegen Music Festival in Ireland on a sunny Sunday, rocking the same outfit she sported earlier in England. The 23-year-old singer made waves last week in Malta at a press conference, where she donned a bondage mask that she described as a contemporary art piece. Gaga expressed her love for second-hand clothing, boldly stating that she believes all the incredible outfits she wears are designed by gay men.
