Team Sexy continued
Tuesday – but this week it was a close one.
results show had a little bit of everything this week: a live performance from an expectant Kelly Clarkson
, coaches Cee Lo Green
and Christina Aguilera
sporting some funky hats, and nail-biting drama, courtesy of the Twitter instant save, which determined who would be sent home.
The show kicked off with a holiday performance of "Underneath the Christmas Tree" by a still-queasy
Clarkson, who didn't move around much onstage, and told host Carson Daly
, "I've felt better. I'm looking forward to the second trimester."
"She's been having a bit of a rough pregnancy just with the sickness and morning sickness," Daly told PEOPLE after the show. "She throws up lots ... [But] she has a great attitude about it."
Later, the show got down the business, gathering the top six onstage to begin revealing their fates after their two performances Monday night
The first singer declared safe? Jacquie Lee
of Team Christina, the youngest singer in the competition at just 16, who earned high marks for her version of Janis Joplin's "Cry Baby" the previous night.
Later, Daly revealed that soulful Cole Vosbury, 22, coach Blake Shelton
's only remaining contestant, was also safe, along with Tessanne Chin
, 28, and Will Champlin, 30, of Team Adam Levine
That left Matthew Schuler
, 21, of Team Christina and James Wolpert, 22, of Team Adam in the bottom two and hoping for the instant Twitter save. It was the second week in a row Schuler found himself in a vulnerable position, although he was saved via Twitter last week.
Both coaches issued heartfelt pleas for their team members, particularly Levine, PEOPLE's Sexiest Man Alive
, who had not had a singer in the bottom three for the past three weeks.
"You had a slightly off week, but I know, and I beg you guys in Twittersphere out there, to save this kid. Because this guy is one of the best singers I've been in a room with. I promise if you save him you will not be sorry," he said passionately.
His speech apparently worked, as Wolpert, an Apple store genius who dropped out of Carnegie Mellon to pursue music, was instantly saved and joins the top five next week.
The semi-finals will air Monday (8 p.m. ET) on NBC.
