All work and no play makes Rihanna the No. 1 artist in the country; not only is her latest single, “Diamonds,” atop the Billboard Hot 100 chart, but her new album, “Unapologetic,” is No. 1 on the Billboard 200 chart.

Released on Nov. 19, “Unapologetic sold 238,000 copies in its first week, according to Nielsen SoundScan, Billboard reports. It’s the singer’s first No. 1 album, while “Diamonds” is her 12th No. 1 single. 

According to the Billboard, it is not uncommon for artists to have several singles reach number one on the Hot 100 chart without having a number one album.

Rihanna’s 2010 album “Loud” debuted at No. 3 with 207,000 copies sold in its first week. The album had three No. 1 singles, “Only Girl (In the World),” “What’s My Name” and “S&M.”

Rihanna has released an album nearly every year since her 2005 debut with “Music of the Sun,” which peaked at No. 10; "A Girl Like Me" peaked at No. 5 in 2006; "Good Girl Gone Bad" peaked at No. 2 in 2007; "Rated R" peaked at No. 4 in 2007; "Loud" and "Talk That Talk" both peaked at No. 3 in 2010 and 2011, respectively.

Rihanna’s success can likely be attributed to her hard work. The singer recently completed her "777" promotional tour for “Unapologetic,” on which the singer performed seven shows in seven locations in seven days, accompanied by a tour plane full of friends, fans and journalists.

Rihanna recently told Nick Grimshaw on the "Radio 1 Breakfast Show" that the tour was so strenuous that she was unable to spend as much time with her guests as she would have liked.

“It was fun. It was exhausting ... it was definitely different doing your job, but with 200 guests coming along with you -- they want you to get drunk after the show. Most of the plane rides were two hours to four hours,” she said.

“I used my time wisely ... I didn't party too hard. I had to save my voice -- sometimes you wish you could give more.”
