"The Voice" crowned a winner of Season 4 last night on NBC in part two of the finale.

The Top 3, Danielle Bradbery, Michelle Chamuel and the Swon Brothers were joined by the rest of the Top 16 contestants from earlier in the year as they did several songs together through out the night. 

In the end, Danielle Bradbery, the youngest one in the competition, gets crowned the winner of Season 4. 

This was no surprise to people who have been watching the show as she has emerged as a favorite under the coaching of Team Blake, which was perfect for her because Bradbery is a country singer and she has a great chance to success in that market. 

Four of the Top 16 ladies came out to do a special performance of "All-American Girl". Finalist Danielle Bradbery was joined by Amber Carrington, Caroline Glaser and Sarah Simmons to sing the song. 

The girls sounded great together, Caroline Glaser's voice definitely stuck out the most as being her own unique sound. It was amazing how similar the other three girls sounded, especially Amber and Danielle. Each girl nailed her parts and got a little time to shine, which was nice to see in the Finale for all the fans of those girls. 

Another big moment was when Christina Aguilera, former judge on "The Voice", returned to the stage to perform at the finale. 

She looked great and her voice was flawless as usual. She seemed to have a confidence about her on stage that was nice to see. 

Pitbull joined her on stage to perform their hit song, "Feel This Moment".  

Christina Aguilera took this season off of judging on "The Voice" but will be back for Season 5 along with original judge Ceelo Green and alongside Adam Levine and Blake Shelton this Fall on NBC.

Bruno Mars, Cher and Florida Georgia Line also performed, along with Bob Seger singing a song with the Swon Brothers.
