LOS ANGELES (CBS/AP) If the dancing isn't enough to get you to tune into the start of another "Dancing With The Stars" season tonight, you might want to do it for the music.

Taking the stage for the opening show will be Pitbull and Justin Bieber, both promoting songs from their new albums.

Pitbull's seventh album, "Global Warming," is due out in November. The rapper-songwriter will perform his new single from that album "Don't Stop The Party."

Bieber, the teen idol, will do the second single from his latest project, "Believe." The single is titled "As Long as You Love Me." "Believe," the 18-year-old singer's third studio album, was released in June.

Meanwhile in the dancing part of the competition, the 13 couples - all familiar faces to "DWTS" fans- will perform in an effort to avoid being the first kicked off the show.

This season's All-Star cast features such former champs as racecar driver Helio Castroneves, gridiron star Emmitt Smith and singer Drew Lachey and fan favorites such as reality TV star Bristol Palin and actresses Kirstie Alley and Pamela Anderson.

Former Disney star Sabrina Bryan was chosen by fans to the 13th competitor on this season's show.

The show is hosted by Tom Bergeron who won an Emmy for his work Sunday night in Los Angeles. Judges are Len Goodman, Bruno Tonioli and Carrie Ann Inaba.

They are really busting out all the stops to make this year bigger than ever. I can't believe they got such high profile talent to come on the show. The performances should be great! I was talking to a coworker at DISH and we are going to watch it together after work since Justin Bieber is going to be on the show. I know for sure that I am going to save this one on my Hopper. I probably have half of its two terabyte hard drive filled with Bieber appearances, and I watch them all the time. He is the most amazing thing in the world, and I only hope that I can come back to reality to watch the rest of the show after his performance.
