STAGE TUBE: Highlights of DWTS Semi Finals

After last week's nerve-racking double elimination, the four remaining couples faced off in the semifinals of ABC's DANCING WITH THE STARS last night.  The couples performed one new Ballroom and one new Latin dance to determine which three couples will land in the finals. View highlights of the show below!

Tonight, TUESDAY, MAY 15 (9:00-10:01 p.m., ET), special musical guests Carrie Underwood and Alanis Morissette will hit the stage with unforgettable performances on "Dancing with the Stars the Results Show." Award winning Country superstar Carrie Underwood is set to perform "Good Girl," the first single off her brand new album, "Blown Away." Her exciting performance will be accompanied by Tristan MacManus, Sharna Burgess, Henry Byalikov and Emma Slater. Multi-platinum, Grammy ® Award-winning artist Alanis Morissette will hit the stage with a world premiere performance of her new single, "Guardian," from her upcoming album, "Havoc and Bright Lights." Her performance will be accompanied by Blake McGrath and Tyne Stecklein.

During Tuesday night's results show we will also have an incredible performance from the upcoming Warner Bros Pictures feature release, "Rock of Ages." The electrifying performance will feature two-time former "Dancing with the Stars" champion Julianne Hough and her co-star, actor/singer Diego Boneta. Directed by Adam Shankman ("Hairspray"), New Line Cinema's adaptation of the smash hit Broadway musical "Rock of Ages" hit theaters June 15th. The movie musical stars Julianne Hough, Diego Boneta, Russell Brand, Paul Giamatti, Catherine Zeta-Jones, Malin Akerman, Mary J. Blige, Bryan Cranston, with Alec Baldwin and Tom Cruise.

In the final "Macy's Stars of Dance" performance this season, two yet to be named "DWTS" pros will perform a riveting Samba to "End of Time." All season long, fans have voted on the performance song, style, costumes and pro dancers for the season's Macy's Design-a-Dance.

Carrie Underwood's brand new album, "Blown Away," made history by debuting at No. 1 on Billboard's Top Country Albums Chart, making her only the second country artist in the 47 year history of the chart to have each of their first four albums debut at No. 1. With more than 267,000 albums sold, "Blown Away" debuted at No. 1 on the all-genre Billboard 200 Chart, making Underwood the only the second country artist in history to have three consecutive albums debut at No. 1. In addition to holding the No. 1 spot on both the Country and All-Genre Album Sales Charts, "Blown Away" also holds the No. 1 spot in digital sales, with more than 107,000 copies sold, making "Blown Away" country's best-selling digital album debut since 2010. Since releasing "Some Hearts" in 2005, Underwood has sold more than 14 million albums with "Some Hearts," 2007's "Carnival Ride," and 2009's "Play On," making her the best selling "American Idol" in the US. She's amassed 14 No. 1 singles, six of which she co-wrote, and became the first country artist in history and the only "American Idol" winner ever to achieve 10 No. 1 singles from their first two albums. Underwood currently leads the nominations for the upcoming CMT Music Awards with five. She is a five-time Grammy ® winner, a two-time Academy of Country Music Entertainer of the Year, a three-time Country Music Association and ACM Female Vocalist winner, and a proud member of the Grand Ole Opry.

Since 1995 Alanis Morissette has been one of the most influential singer-songwriter-musicians in contemporary music. Her deeply expressive music and performances have earned vast critical praise, 12 Canadian Juno Awards, 7 Grammy® Awards (with an additional 14 nominations), a Golden Globe nomination and sales of over 60 million albums worldwide. Morissette's 1995 debut, "Jagged Little Pill," was followed by such eclectic and acclaimed albums as "Supposed Former Infatuation Junkie" (1988), "MTV Unplugged" (1999), "Under Rug Swept" (2002), "Feast on Scraps" (2002), "So-called Chaos" (2004), "Jagged Little Pill Acoustic" (2005), her greatest hits album, "The Collection" (2005), and "Flavors of Entanglement" (2008).

Most recently Alanis has acted on the small screen with roles in hit television series "Weeds" and "Up All Night", and has appeared as a celebrity guest mentor on the current season of "The Voice." Alanis' forthcoming seventh studio album, "Havoc and Bright Lights," is scheduled to release on August 28th, 2012 through Collective Sounds/Sony RED.
