Janet Jackson

Less than two weeks before R&B superstar Janet Jackson's eagerly awaited new album, "20 Y.O.," hits stores, the lead single, "Call on Me," has claimed the Number One slot on "Billboard's" Hot R&B/Hip-Hop chart, which is based on a combination of radio airplay and sales.

The Janet/Nelly duet is the music icon's 15th Number One and 30th Top 10 single on the Hot R&B/Hip-Hop Songs chart. Janet is now tied with R. Kelly for scoring the most Top 10 singles since "Billboard" began compiling its information from Nielsen SoundScan data in 1992. She tops the R&B chart, in existence for 64 years, ahead of all artists since 1984.

The second single from "20 Y.O.," the steamy dance-pop track "So Excited," hearkens back to Janet's career-making 1986 album "Control." The track, which features rapper Khia, hit radio on August 28th, while a sexy companion video clip, lensed by award-winning director, Joseph Kahn, debuted on BET's "Access Granted."

On September 25th, the day before "20 Y.O." is released, Janet will appear on "The Oprah Winfrey Show" to chat with Oprah and sing "So Excited." She will also excite hundreds of fans in New York City when she performs three songs on NBC's "The Today Show" on September 29th.

In addition, look for Janet this month on the covers of "W," "FHM," "Giant," "Ebony," and "Billboard" magazines.
