Somebody ring the alarm — because Ed Sheeran is bringing back an old classic. While performing at BBC Radio 1’s Live Lounge Tuesday, the British crooner decided to revamp Christina Aguilera‘s ‘Dirrty,” performing a more soulful and acoustic version of the 2000 single. Obviously proud of his efforts, the 24-year-old even invited Aguilera to listen to this rendition, writing on his Twitter, “Oi @xtina I covered you.”
