Rihanna is the queen of the charts as she becomes only the second artist this year to simultaneously rank No. 1 on both the Billboard Hot 100 and the Billboard 200.

Diamonds” sparkles for a second week as the leader on the singles chart, while “Unapologetic” bowed at No. 1 on the Billboard 200 this week.

Not surprisingly, Adele is the only artist to achieve that feat in 2012 in February, when “21” led the album chart and “Set Fire To the Rain” was No. 1 on the Hot 100, according to Billboard.

Rihanna fends off a challenge from Ke$ha, whose “Die Young”  climbs 3-2. Ke$ha’s track trades places with Maroon 5’s  former No. 1 smash, “One More Night, “ which drops to No. 3.

Bruno Mars snags another Top5 hit as “Locked Out Of Heaven,” the first single from “Unorthodox Jukebox,” rises 7-4. Psy’s “Gangnam Style,” which was locked out of the No. 1 spot by Maroon 5, rises 7-5.



Rounding out the bottom half of the Top 10, fun.s’ “Some Nights” slides 5-6, while the Lumineers’ “Ho Hey” creeps up a spot to No. 7.  No new songs enter the top 10, but “American Idol” champ Phillip Phillips’s “Home” makes a welcome return as the song bounces 12-8 on the strength of the release of his debut album, “The World From The Side of the Moon.”  The song had previously peaked at No. 9.

Flo Rida’s “I Cry” inches  10-9, while Ne-Yo’s “Let Me Love You (Until You Learn To Love Yourself” falls 6-10.
