Rihanna Breaks Billboard Chart Records With 'S&M'

Rihanna's 'S&M' will hit No. 1 on Billboard's Hot 100 today (April 21), marking the Barbados-born singer's 10th No. 1 single.

With the Britney Spears-aided 'S&M (Remix)' giving her fourth single off the 'Loud' album a bit more push, Rihanna will attain the honor of scoring 10 No. 1's on Billboard's Hot 100 in the shortest span of time. She recorded her first No. 1, 'SOS,' just four years, 11 months and two weeks ago. The singer also beat out labelmate Mariah Carey by almost five months.

Not only did Rihanna beat Mariah to the chart record in a shorter period of time, but at 23, she's also the youngest artist to notch 10 No. 1's in the chart's 52-year history, besting Mariah again, who was 25 when she scored her 10th single.

"10th!!!!!Now LOOK at what u did ... THANK U so much, this is the BEST news!" Rihanna tweeted. "BIGUP to @britneyspears and all her wonderful fans who supported this song."

The red-haired phenom is the ninth artist to achieve 10 No. 1 singles, and the fifth solo female, following Janet Jackson, Whitney Houston, Madonna and, of course, Mariah, with a whopping 18 No. 1 hits to her credit.

"Rihanna's tenth #1 single is a monumental accomplishment and a testament to her incredible artistry," said Island Def Jam President Steve Bartels. "This was a truly collaborative and creative effort, spearheaded by Rihanna's tireless work and aided in no small part by the incredible Britney Spears and her team. I am extremely proud of Rihanna."

Rihanna's Grammy-winning fifth album 'Loud' was released on November 12.

Rihanna and Taylor Swift Want to Charge You for Tap Water

You know when you go to a restaurant and instead of ordering a $5 soda, you decide to just go with a glass of water? Well if Rihanna and Taylor Swift have their way, you're going to start paying for that glass of tap water soon too.

They've added their name to Unicef's Tap Project, which urges restaurants to start charging at least $1 for tap water.

In one of the advertising posters, Rihanna poses next to a bottle of her personalized drink with the words, "Rihanna Tap Water. Not your typical tap water, unless of course, you live next door to Rihanna."

A message on the Unicef Celebrity Tap website reads, "Celebrities have donated their own tap water to help raise awareness of the world water crisis. Donations enter individuals in our sweepstakes to win an esteemed collection of these famous tap waters."

I'm all for Unicef raising...
