Justin Bieber, Ke$ha, Katy Perry Pick Up Platinum Certifications

Releases by Black Eyed Peas, Rihanna, B.o.B, Bruno Mars also recognized by recording-industry organization RIAA.

On Wednesday, the Recording Industry Association of America handed out their latest round of gold and platinum certifications ... and if your name was Ke$ha or Justin Bieber, well, then it was a very good day for you.

Ke$ha's Animal was certified gold (meaning it passed the 500,000-sales mark) and a spate of her digital singles went multiplatinum, with "Tik Tok" being downloaded more than 5 million times and "Your Love Is My Drug" racking up another 2 million. "Blah Blah Blah" and "Take It Off" both were certified gold, meaning that, all told, she's sold more than 8.5 million downloads to date.

Bieber earned his first-ever multiplatinum award, as the RIAA certified sales of his My World 2.0 album at more than 2 million copies. "Baby," his team-up with Ludacris, also was certified as double platinum.

Wednesday also was a great day to be the Black Eyed Peas, as their massive tune "I Gotta Feeling" was certified 6-times platinum (that's more than 6 million downloads) — making it the RIAA's highest-ever digital-song certification.

Following (somewhat) close behind the Peas were the likes of Katy Perry, B.o.B, Taio Cruz and Rihanna, who had their respective mega singles "California Gurls," "Airplanes," "Break Your Heart" and "Don't Stop the Music" certified as triple platinum. Perry and Rihanna also each picked up a double-platinum certification — for "Teenage Dream" and "Rude Boy," respectively — bringing their total hauls to more than 5 million units sold.

The Bruno Mars track "Just the Way You Are" was certified platinum, giving the crooner his very first solo plaque. B.o.B's "Magic" and former "American Idol" champ Kris Allen's "Live Like We're Dying" also picked up platinum certifications.
