The Voice coaches finalized their teams Monday night, and it sounds like the battle to win it all might be epic.
All four coaches nabbed some powerhouse talent during the blind auditions, and all are itching for a win.
But who will emerge as The Voice victor?
Here are our picks for the ones to watch:
Christina Aguilera is sitting pretty.
She's back in the red chair for season 5 of The Voice and says she feels sexier than ever.
Thanks to some time off, a new fitness routine and healthy eating, Aguilera has put in the hard work to slim down – but says her family is still a priority over exercise.
"If I have to choose between working out and spending time with my son after a hard day, it's not even a question," Aguilera tells November's Redbook, on newsstands Oct. 15.
A stressed-out single mom and a former contestant seeking redemption scored the two four-chair swivels of the night Tuesday as The Voice's coaches inched closer to completing their teams during the fourth night of blind auditions.
The coaches' powers of persuasion – and sharp elbows – were on full display during the final showstopping performance of the night when Ashley DuBose, a single mother/programmer analyst from St. Paul, Minn., arguably outshone Rihanna while singing the Grammy winner's hit "Diamonds."
"Your voice cuts like a razor through this entire place," coach Adam Levine told the 23-year-old. "Those are the voices that make it real far on this show."
It may be Kaley Cuoco's week to shine, as she announced her engagement, but it was little sister Briana who took her turn in spotlight Monday as a talented contestant on The Voice.
Briana, who works as Kaley's personal assistant, won over coach Christina Aguilera easily as she sang Lady Gaga's hit "You and I," earning kudos for her raw talent and power.
"You held those notes out really strong. You made me really happy," Aguilera told her, handily earning Cuoco's trust over competitor Cee Lo Green.
"Girl power!" Cuoco screamed as she picked Aguilera as coach.
Said proud sister Kaley, teary-eyed: "She's always put herself on the back burner for everyone else. There is no one who deserves this more." Watch Briana's audition below.
Powerhouse performances and power struggles dominated the second night of The Voice's blind auditions Tuesday, which included two four-chair turns and even gave an '80s cult actress a second chance at stardom.
"The fabulous four," as returning coach Christina Aguilera dubbed the reunited coaching panel at the top of the show, duked it out throughout the night as they each vied to persuade their favorite singers to join their teams.
At the top of everyone's list was Tessanne Chin, a Jamaican singer who closed out the night with a fierce version of Pink's "Try."
Season 5 of The Voice kicked off with an energetic premiere and its first blind auditions on Monday, featuring two returning star coaches and the sparring chemistry of seasons past.
Soul man Cee Lo Green was back with Michael Jackson's wardrobe and his trademark quips. Three-time winner Blake Shelton and his show nemesis Adam Levine resumed their snarky sparring. Also back and raring to win was a gam-o-licious Christina Aguilera, who represented with spunky girl-power, throwing off sex appeal and a lot of shapely leg.
The contestants brought their A-game, too, and some cute stage bravado. "What's goin' on, handsome?" said musical theater buff Nic Hawk, nakedly flirting with Levine, but only after killing Blu Cantrell's "Hit Em Up Style (Oops)."
Christina Aguilera feels sexier than ever – and it shows.
The super svelte pop star and Voice coach popped by The Tonight Show with Jay Leno Wednesday night in a little black dress, and talked frankly about her ability to enjoy herself between the sheets.
The singer added to comments she recently made to Maxim magazine, when she declared that "the one place I do not need to be in control is the bedroom."
Talk about chair-spinning.
As these samples show, a sizzling Christina Aguilera is showing off her assets in October's Maxim, in a spread titled "The Voice and The Body."
The Voice coach, who returns this season, shows off a new and slimmer body in some sexy lingerie.
She loves you. She really, really loves you.
The often-reticent Christina Aguilera expressed her emotions in a big way late Wednesday, posting a long letter to fans on her website – a 2,200-word meditation on art, love, struggle and transcendence in which she frames her own ideas of success in a business dominated by style rather than substance.
"I may get quiet at times, but when I do have something to say, I mean every word," The Voice coach, 32, writes. "I decided to share my thoughts with you at length and tell you openly how I feel."
Breaking up is hard to do, especially if there are children involved.
If anyone can relate to the pain endured from parents getting divorced, it's season 3's winner of The Voice, Cassadee Pope, whose new song, "11" was released on iTunes Tuesday.
"They got married and started having kids really young, so I think things changed really quickly for them," Pope tells PEOPLE about living through her parents' split when she was 11.
