American Idol” fans are in for what sounds like another exciting show! Thursday’s episode 19 will reveal Season 15’s top five finalists, as well as feature performances by “American Idol” alum Adam Lambert and “Empire” stars Jussie Smollett and Bryshere “Yazz” Gray.

According to Entertainment Weekly, Lambert will take the “Idol” stage to perform his new song “Welcome to the Show,” which dropped earlier today.

“I wanted to surprise my fans with a new, uplifting anthem for the spring,” Lambert said. “I asked Max Martin for help and he paired me up with two great writers and producers: Ali Payami, who worked with me on ‘Ghost Town,’ and Swedish star Laleh who is also a featured vocalist on the track. I feel this song will give people strength to be exactly who they are.”

WTIC-TV reports that Yazz and Smollett will also sing a new song, “Never Let It Die,” which is featured in the background of the Season 2 trailer for “Empire.”

As with each episode, judges Jennifer Lopez, Harry Connick Jr. and Keith Urban will use their “Judges Save” at the end of the show to keep one of the bottom contestants in the competition. However, instead of three “American Idol” hopefuls at the bottom, it will only be two this week.

According to American Idol Net, contestant Trent Harmon revealed to fans that this week each contestant will sing two solo songs. Since the theme for the show is America’s Choice Night, the contestants will perform songs chosen for them by fans.

The contestants have kept quiet about which tunes they’ll tackle, but mentor Scott Borchetta revealed a few of the song choices in an interview with Taste of Country. Sonika Vaid will sing “Clarity” by Zedd, Dalton Rapattoni will tackle “The Sound of Silence” by Simon and Garfunkel and La’Porsha Renea is singing “No More Drama” by Mary J. Blige. Michael Jackson’s “Billie Jean” will be sung by MacKenzie Bourg, Harmon will perform Lynyrd Skynyrd’s “Simple Man” and country singer Tristan McIntosh will step outside her comfort zone with “It’s My Life” by Bon Jovi.

Borchetta also revealed that a few of the contestants have been suffering from vocal issues and had to take it easy this week.

“When we get to these last four weeks of the farewell season, all of them are feeling pretty ragged at this point,” he told Taste of Country. “There have been a lot of seven-day weeks. It does get pretty wearisome at this point.”

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