'The Voice' season 7 Battle Rounds have started and things are starting to heat up!
Coaches Adam Levine, Blake Shelton, Pharell, and Gwen Stefani finally brought in their musical friends (and family member) to help them mentor the 12 contestants in their respective teams.
Levine asked for help from legendary artist and Fleetwood Mac's lead singer, Stevie Nicks, while Shelton had Grammy-winning country group Little Big Town join in during his group's rehearsals.
Pharell surprised his team with a little help from multi-Grammy winner Alicia Keys. Stefani, on the other hand, kept it in the family with husband Gavin Rossdale sharing his insights during practice.
Team Pharell proved to be a strong team with two of his group members giving one of this week's best battle performances.
Luke Wade and Griffin, with Alicia Key's help, performed an Aretha Franklin-inspired version of Paul McCartney and the Wings' 'Maybe I'm Amazed.' They pulled it off so well that Pharell had a hard time choosing who would win.
Eventually, Luke Wade won this round but Griffin was quickly stolen by Blake Shelton.
Another great performance from Pharell's team was the 'If I Ain't Got You' duet by 16-year-old Elyjuh Rene and Yale graduate Maiya Sykes. Rene won this round.
Taylor Phelan and Jordy Searcy also battled it out with a slowed-down version of 'Breakeven' by The Script and Pharell chose Phelan to move on to the Knock Offs.
'The Voice' season 7 Battle Rounds isn't over yet. More duets will be heard on Monday making the tension run high for the coaches, as well as bring in more unpredictable moves.
Gwen Stefani already surprised everyone by using her first steal to get veteran country singer Craig Wayne Boyd from Shelton.
So far, Team Pharell has Elyjuh Rene, Taylor Phelan, and Luke Wade going to the next round. He also stole Menlik Zergabachew from Stefani. Team Gwen stole Craig Wayne Boyd and chose Sugar Jones, Taylor John Williams and Troy Ritchie for the Knock Offs.
Team Adam has Chris Jamison, Alessandra Castronovo, and Rebekah Samarin. Team Blake on the other hand chose James David Carter, Grant Ganzer, Tanner Linford, and the "stolen" singer Griffin.
