The University of Tennessee student's cause of death is currently under investigation as police await toxicology reports.
Swift attended the 21 year old's funeral on Monday (08Nov10) and just 24 hours later, she took the stage at the glitzy awards show in Nashville to pick up two prizes, and she used the opportunity to pay tribute to her late friend.
She told the crowd, "It's been a really emotional week... He was 21, and I used to play my songs for him first. So I would like to thank Jeff Lang."
