Rihanna's "S&M" moves up to #1 on the Hot 100 after three weeks at #2. This is Rihanna's 10th #1 hit, which is remarkable when you consider that she is just 23. Only three other artists in chart history have amassed 10 #1 hits before their 24th birthdays.

All three members of the Supremes (Diana Ross, Mary Wilson and Florence Ballard) were 23 when they landed their 10th #1 hit, "The Happening," in May 1967.

Paul McCartney was 23 and George Harrison was just 22 when the Beatles landed their 10th #1 hit, "Yesterday," in October 1965. (Ringo Starr and John Lennon were both 25. In fact, Lennon turned 25 on the day the song hit #1: Oct. 9.)

Elvis Presley was 23 when he landed his 10th #1 hit, "Hard Headed Woman," in July 1958.

Only eight other artists have amassed 10 or more #1 hits since July 1940, when Billboard introduced its first  national top 10 popular songs chart. For the sake of comparison, here's how old these artists were at the time they landed their 10th #1 hits, together with

Adele's 21 returns to #1 on The Billboard 200 for a fourth week. That's the longest run at #1 since Taylor Swift's Speak Now topped the chart for six weeks starting in October. 21 also becomes the first album to sell 1 million copies in the U.S. this year. The album has sold 1,030,000 copies in its first seven weeks. That's slightly more than Adele's previous album, 19, has sold in its entire run. That album (which is #1 on the Catalog Albums chart for the seventh week) has sold 1,015,000 copies since its release in June 2008.

21 is performing even more impressively in the U.K., where it holds at #1 for the 11th week. This puts it in a tie with Shania Twain's Come On Over and Alanis Morissette's Jagged Little Pill as the longest-running #1 album by a female solo artist in the 55-year history of the U.K. album chart.

An all-female group and a duo with a female lead singer had even longer runs at #1 in the U.K. than these three female solo artists. The Spice Girls' Spice logged 15 weeks

Britney Spears this week becomes the first female solo artist in the history of Billboard's pop album chart to amass six #1 albums before her 30th birthday. Spears, 29, achieves the feat with her new album, Femme Fatale, which enters the chart at #1. Until this week, Mariah Carey was the youngest female solo artist to gather six #1 albums. She was 38 when she picked up her sixth #1 album, E=MC2, in 2008.

Only two male solo artists have notched six #1 albums before turning 30. Elvis Presley nabbed his sixth #1 album (1961's Something For Everybody) when he was just 26. Elton John landed his sixth (1975's Captain Fantastic And The Brown Dirt Cowboy) when he was 28.

Only four other female solo artists have amassed six or more #1 albums (no matter their age). Barbra Streisand leads the pack with nine, followed by Madonna with seven and Mariah Carey and Janet Jackson with six each.

Femme Fatale sold 276,000 copies in its first week, which is the second biggest one-week total so far in 2011.

Katy Perry's "E.T." (featuring Kanye West) jumps to #1 on the Hot 100. It's the fourth consecutive #1 hit from Perry's sophomore album, Teenage Dream. It follows "California Gurls" (featuring Snoop Dogg), "Teenage Dream" and "Firework." Perry's album is the first since Usher's Confessions in 2004 to spawn four #1 singles. It's the first by a female artist to yield four #1 hits since Mariah Carey's eponymous debut album in 1990-1991.

Only six other albums have spawned four or more #1 hits on the Hot 100. Michael Jackson's Bad, which generated five #1 hits in 1987-1988, leads the pack. Albums that have spun off four #1 hits are the Saturday Night Fever soundtrack (1977-1978), Whitney Houston's sophomore album Whitney (1987-1988), George Michael's solo debut Faith (1987-1988), Paula Abdul's debut album Forever Your Girl (1989-1990) and Janet Jackson's second album as a major star, Janet Jackson's Rhythm Nation 1814 (1989-1991).

These nine albums all but define the term "mass appeal."
