X-Factor Live Stream Free: Watch Online Top 8 Double Elimination Show @ 8PM ET

The top 8 singers of The X Factor contest took to the stage last night and sang No. 1 songs. Tonight two contestants are expected to head home. Fans are able to tune in to see who will be eliminated on this Thursday's show, which will air live on TV at 8 p.m. ET, with the show also available to be watched online through free live stream (see details below).

On Wednesday's show the singers took more risk in their song choices as they scrambled for a top 6 spot. Some got it right while others apparently not, according to the judges' comments.

Britney Spears' Teens:

Diamond White was the first to take the stage, singing Whitney Houston's "I Wanna Dance With Somebody." Diamond received mostly positive reviews.

"It's amazing to see you walk onstage and have fun during a song," said Demi Lovato.

However, L.A. Reid thought that Diamond always seems to "start slow" and then "get there."

Carly Rose Sonenclar chose Adele's "Rolling in the Deep" and was commended by the judges.

"I thought the first half of the song was good, I thought the second half of the song was sensational," said Cowell.

Demi Lovato's Young Adults:

Paige Thomas took more risk than usual in her song choice and sang Rick Astley's "Never Gonna Give You Up," which had backup dancers. For Reid, this was her best performance so far, and for Cowell, "This is the first time you have looked and sounded like a legitimate pop star."

CeCe Frey sang Patti Labelle's "Lady Marmalade."

The contestant was fighting to get out of the bottom position. However, Cowell thought her performance gave "too much." He said, "You gave me too much. There was way too much going on. Too distracting....My advice tonight is pack a suitcase."

L.A. Reid's Over 25's

Vino Alan sang "You've Lost That Loving Feeling" by his mentor, a song that was chosen at the last minute. Simon Cowell said "That was not a $5-million performance."

Tate Stevens played guitar this week singing Keith Urban's "Somebody Like You."

Britney Spears commended him saying, "I'm sure we'll be seeing you accept a country music award some day, you're brilliant."

The singer also impressed Lovato as he dedicated his performances to his wife. "One day, when I get married, I want someone to love me as much as you love your wife," she said.

Simon Cowell's Groups

Fifth Harmony, dealing with the death of member Ally's grandfather, took the stage and sang Kelly Clarkson's "Stronger (What Doesn't Kill You)."

For Cowell, the group gave a "Fantastic performance" and for Britney the song really worked for them.

Emblem3 sang the Monkees "Daydream Believer" and pleased most of the judges.

"You guys have turned into real pop stars," Cowell said.

The show will air Thursday, Nov. 29 at 8 p.m. ET live on Fox. The show can also be watched online through free live stream by clicking here.
