The Knockout Round is kicking off this week on The Voice. The artists get to pick their own songs to perform and be mentored by guest advisor, pop star Miley Cyrus, who will be a coach in Season 11. (Pharrell and Christina Aguilera are leaving the show. Alicia Keys will join too.) A lot is on the line for the contestants during the Knockout Round. The judges have just one steal left to lose.
If you think having Christina Aguilera and Miley Cyrus on the same stage at the same time is going to be too much to handle, don’t worry. Aguilera is helping America digest by changing her hair style. Since her return this season, Xtina’s been wearing her hair most often in a big, messy half-pony (see photo below). With Miley on the show (wearing a big "I Dream of Jeannie" ponytail), Xtina is opting for a classy, smooth, straight do. The Voice airs Mondays and Tuesdays at 8pm on NBC.The BEST SALES on Amazon NOW ]
