Kelly Clarkson, Gladys Knight Perform on DANCING WITH THE STARS Finale Tonight, 5/22

In the two-hour Season Finale of Dancing with the Stars tonight, May 22 (9:00-11:00 p.m., ET), the excitement will continue with a stunning opening number with the entire cast and the Troupe. Tonight, all of this season's eliminated couples will return to the ballroom to perform some of the most memorable routines, as well as a few new surprises, including a special musical performance from Grammy® Award-winning Gladys Knight, who will accompany a dance performance. Grammy® Award-winning superstar Kelly Clarkson will also light up the ballroom singing a medley of her hit songs "Dark Side" and "Stronger," accompanied by Kym Johnson, Tony Dovolani, Anna Trebunskaya, Tristan MacManus and the Troupe. And in the final element of the competition on Tuesday, the three finalists perform a new routine in our "24 Hour Challenge" - in which they will have had 24 hours to pair their dance style of choice to music given to them after Monday night's show. This routine will be scored out of 30 and will round out the judges' scores across both nights.

Since bursting onto the music scene 10 years ago, Kelly Clarkson has released 5 studio albums, sold over 20 million albums worldwide, 10 million albums in the US and has had 10 singles in the top 10 on the Billboard Hot 100 Singles Chart. She is the recipient of 2 Grammy ® Awards, 4 American Music Awards, 3 MTV Video Music Awards, 2 Academy of Country Music Awards, 1 Country Music Association Award and 12 Billboard Music Awards. Clarkson's most recent effort, "Stronger," debuted at No. 2 on both the Billboard Top 200 and Digital Albums Chart. The album is certified Gold by the R.I.A.A. and produced the smash singles, "Mr. Know It All" and "Stronger (What Doesn't Kill You)," which marks Clarkson's 9th and 10th Top 10 hit. "Stronger (What Doesn't Kill You)" was No. 1 on Billboard's Hot 100 Chart for two consecutive weeks (3 weeks total), her 3rd No. 1 hit on the Hot 100 Chart. She is set to tour this summer with The Fray as well as will star in ABC's new reality competition, "Duets," which premieres May 24.

Eight-time Grammy® winner Gladys Knight has enjoyed No. 1 hits in pop, R&B and Adult Contemporary, and has triumphed in film, television and live performance. The Georgia-born Knight began performing recitals at age 4 in the Mount Mariah Baptist Church. Three years later, in 1952, she won the grand prize on television's "TEd Mack's Amateur Hour," and the following year she, along with her brother, Bubba, and her cousins, formed The Pips and had their first hit in 1961. In 1962 the group was renamed Gladys Knight & The Pips and went on to achieve icon status, recording some of the most memorable songs of the 1960s, 1970s and 1980s. Knight has recorded more than 38 albums over the years, including four solo albums during the past decade. She recently released her newest album, featuring the hit "I Who Have Nothing." A longtime Las Vegas resident, Knight returned to the Strip this past year at the famed Tropicana Hotel for a special engagement that ran in the newly named Gladys Knight Theater, making her the first African-American performer to have a venue named after her in Las Vegas.
