'The Voice' NBC Season 7 Finale Bruno Mars 'Uptown Funk' Live Performance Wearing Gold Hair Rollers, Watch Here (VIDEO)

"The Voice" Season 7 wrapped up their two-night finale on Tuesday night (Dec 16) and before a winner was announced there was a long line of special guest performances lined up. 

Bruno Mars & Mark Ronson brought the house down with a performance of their new hit single "Uptown Funk". Bruno even was rocking what appeared to be gold rollers in his hair during the performance. You can watch the clip above. 

NBC pulled out all of the stops for the evening with performances also by Ed Sheeran, Jessie J, Meghan Trainor, Lynard Skynard, Hozier, Jennifer Hudson, Fall Out Boy and more.

The final 4 contestants going for the Season 7 win were: Matt McAndrew (Team Adam), Damien (Team Adam), Chris Jamison (Team Adam) and Craig Wayne Boyd (Team Blake). 

At the end of the two-hour show, the moment came to announce "The Voice" Season 7 winner and it was... Craig Wayne Boyd!

Not only was this a special win because Craig had been struggling as a musician for so many years, but he also was a 'steal' from Team Gwen and had not really been considered a real threat to win the season until the final few weeks. He also helped Team Blake have another improbable comeback victory over Team Adam. 

The final 4 for the finale was controlled by Team Adam who had his top three remaining: Chris Jamison, Damien and Matt McAndrew. However, all Blake needed was Craig to give Team Blake his fourth victory in seven seasons. 

"The Voice" Season 8 will bring the return of Christina Aguilera, so Gwen will be stepping aside but Pharrell will be back!
