And then there were six. “American Idol” Season 15 narrowed its Top 8 finalists to the Top 6 during Thursday’s episode 18. This week on the Fox singing competition show, the contestants had to perform duets before host Ryan Seacrest revealed which of them had been voted by America into the Top 6.

Just like last week’s show, the bottom three contestants had to fight for the last spot. It was up to judges Jennifer Lopez, Harry Connick Jr. and Keith Urban to decide which one out of the bottom three stayed in the competition and which two were sent packing. The judges had a tough call to make this week as three fan-favorites ended up in the bottom.

The show kicked off with La’Porsha Renae and Trent Harmon’s soulful duet of “See You Again” by Wiz Khalifa and Charlie Puth. La’Porsha said she was nervous to perform a Wiz Khalifa song but she and Trent should be glad they stuck with it. All three judges had nothing but positive things to say about their performance and agreed that it was a good way to kick off the episode.

Unfortunately, for the remaining groups the feedback from the judges wasn’t as glowing as Trent and La’Porsha’s. Avalon Young and Sonika Vaid went with Andra Day’s hit song “Rise Up,” but it appears their duet fell a little flat. Connick Jr. said Avalon performed the song better because her voice is “more rhythmic,” while Lopez told the ladies they should have let go a little bit more while on stage.

The judges also agreed that Tristan McIntosh did better in her duet with Lee John. The pair performed Aerosmith’s “I Don’t Want To Miss A Thing.” Connick Jr. bluntly told Lee and Tristan that it was “very bland” and “very boring.” Urban told the pair that he liked the song but said it was probably difficult to find something they would both be good at. Tristan is a country singer and Lee tends to lean more towards pop music. Lopez wasn’t too impressed with their duet either and simply said it could have been better.

The pair to receive the harshest critiques was probably Dalton Rappatoni and MacKenzie Bourg. Like Lee and Tristan, their pairing was challenging because they sing different genres of music. MacKenzie, who’s become known for his song writing skills, is more pop and Dalton has a more rocker vibe. Regardless, MacKenzie and Dalton put their talent together to perform Backstreet Boys “I Want It That Way.” Lopez joked that she “didn’t want it that way” and Connick Jr. said it wasn’t the right song for them to sing together.

After the duet rounds was the solo performances and the Top 6 reveal. Lopez, Connick Jr. and Urban praised La’Porsha’s rendition of “Come Together” by The Beatles, and they all liked MacKenzie singing Joe Cocker’s “You Are So Beautiful To Me.” Trent also made it into Top 6 and impressed the judges by doing a power rendition of Ben E. King’s “Stand By Me.” Dalton’s “Eleanor Rigby” by The Beatles and Tristan’s “A Broken Wing” by Martina McBride also seemed to win over the “American Idol” judges.

This week in the bottom three were Sonika, Lee and Avalon and after watching all three contestants perform the judges chose Sonika to remain in the competition. That meant Lee and Avalon were eliminated.

“American Idol” airs Thursdays at 8 p.m. EST on Fox.
