'The Voice': Justin Bieber Brings 'Boyfriend'; Ashley De La Rosa And RaeLynn Eliminated (VIDEO)

The April 17 installment of NBC's "The Voice" (Mondays at 8 p.m. ET and Tuesdays at 9 p.m. ET) was filled with cheers and tears. After the previous' night's surprise eliminations -- leaving Team Christina down Jesse Campbell and Team Blake without Jordis Unga -- it was time to send one more contestant home from each team.

Plus, it was also time for Justin Bieber to make a live appearance to present the world premiere of a portion of his new video for "Boyfriend." Bieber, who could barely be heard over the screams in the studio, also announced that his new album will be released on June 19 and that he'll be back on "The Voice" finale to perform "Boyfriend" on live TV for the first time.

But as the pop star exited the stage, he approached each judge and it looked like Christina wasn't a Bieber fan, giving him the side eye as he worked judges and the crowd.

Later, Aguilera told Us Weekly with a laugh, "[Bieber] was a fun burst of energy. He's a really charismatic guy and it was cute!"

But back to the episode. After the tween shrieking dissipated, it was time to move on to the emotional eliminations.

America's votes saved one member Team Christina and another from Team Blake. Apparently, it was boys' night because opera singer Chris Mann and Alicia Keys' former back-up singer Jermaine Paul respectively won the most votes.

For Team Christina, that left young pop rocker Ashley De La Rosa and alternative artist Lindsey Pavao to prove themselves to their coach. Country singer RaeLynn and belter Erin Willett were the ones who had one last chance performance on Team Blake.

Ashley sang Lady Gaga's "You and I" and Adam said it wasn't her best. "Regardless of this performance, I'd keep you around because you're amazing," he assured her. Blake agreed and added that between Lindsey and Ashley, he'd buy Ashley's record.

Lindsey Pavao put her own spin on Mike Posner's "Please Don't Go." By the end of it, she broke down and even Christina started shedding some tears. Cee Lo said he sees "charm" in her and Blake said "there's something so mysterious about her that it draws you into her." Still, he maintained, he'd go with Ashley.

But Christina didn't agree. After a tearful Christina declared her love for both young women, she decided to save Lindsey, sending Ashley home.

Then, Team Blake's bottom two took the stage. Erin Willett opted for Tina Turner's "Proud Mary" and a still visibly shaken Christina said she put in an amazing effort. Then, RaeLynn performed The Band Perry's "If I Die Young." Adam commended the young star because he said, "The song doesn't play her; she plays the song." However, he still didn't think it was her best.

Like Christina, Blake said he loved both of his team members. Eventually -- after much rambling and host Carson Daly pressuring him for a name -- Blake decided to save the more seasoned Erin Willett, sending his youngest team member RaeLynn back to Texas.

Next week, Team Adam and Team Cee Lo will be the ones under pressure. Who do you think will move on to the semi-finals? And did Blake and Christina make the right decisions? Let us know what you think in the comments below!
