POTW: Kanye West, Katy Perry, Chris Brown, Britney
Kanye West and Katy Perry share a few jokes while rocking their hater blockers at the Ready to Wear Autumn/Winter 2011/2012 show during Paris Fashion Week at Pavillon Concorde in Paris March 8.

ALL FOUR ONE: Thanks to a space-age love song, Katy Perry blasts into rarified chart air, as her "Teenage Dream" album becomes only the ninth set to generate four No. 1s in the Billboard Hot 100's 52-year history.

The collection's fourth single, "E.T.," featuring Kanye West, rises 2-1 as the chart's Airplay Gainer and follows "California Gurls," featuring Snoop Dogg, the title cut and "Firework" to the top spot.

"I am so thrilled that 'E.T.' has landed at No. 1," Perry told Billboard.com. "I want to thank all the fans who contributed to this amazing feat and radio, which has been an essential part of my continued existence.

"I truly appreciate all the support of my creative twists and turns."

Here is a look at the elite nine albums - all of which topped the Billboard 200 - to produce at least four Hot 100 No. 1s. The "Saturday Night Fever" soundtrack earned the honor courtesy of two acts: the Bee Gees (three leaders) and Yvonne Elliman (one). Michael Jackson's "Bad" is the sole effort to yield five Hot 100 toppers.

Noticeably, six of the nine sets sporting four or more Hot 100 No. 1s joined the select club between 1987 and 1991. Possible contributing factors include that era's focus on mass-appeal music just before pop radio splintered into more extreme hip-hop and alternative directions.

Also, beginning the week of Nov. 30, 1991, the Hot 100 adopted Nielsen BDS airplay and SoundScan sales data, resulting in slower turnover among No. 1s since.
