Kelly Clarkson comes home to 'American Idol' April 1

The live rounds are underway for the "American Idol" contestants, now having 9 performers in the game. What a better way to kick off the rest of the season than by having its inaugural winner back on the show to promote her sixth studio album Piece by Piece. Ryan Seacrest annnounced on last night's episode (March 25) that Kelly Clarkson will be back on the show on April 1 to mentor and perform for the episode.

Clarkson's last appearance on the show was in early 2013 about this time to promote the second single from Greatest Hits: Chapter One. Clarkson performed "People Like Us" with glow paint and glow sticks for the audience. Keith Urban was seen clearly enjoying her energetic performance followed by an equal admiration between Clarkson and then judge Mariah Carey. The two have met when Clarkson's career began but Carey praised Clarkson of the cover songs from her catalog she's performed over the years.

Kelly Clarkson is promoting her latest pop record Piece by Piece released via RCA Records, the label she signed with after winning the first season of "American Idol" on Sept. 4, 2002. Her current single "Heartbeat Song" hasn't performed as well as a Clarkson song can but became a Top 40 hit on the Hot 100 and in seven countries around the world. Clarkson has expressed "Invincible" penned by Sia would be the follow up single. "Idol" would be an appropriate event to debut.

Since winning "Idol," Kelly Clarkson has gone on to sell over 25 million albums worldwide. Two of her albums, Breakaway and Stronger, have earned her a Grammy for Best Pop Vocal Album, the only artist to win the category more than once.

"American Idol" is live on FOX on Wednesday at 8 p.m. Kelly Clarkson will also perform on the iHeartRadio Awards Sunday night on NBC.
