Beliebers Download Justin Bieber's 'Boyfriend' To Tune Of 500K

Singer's first Believe single sells more than 500,000 copies in its first week.

As expected, Justin Bieber's new single "Boyfriend" has made an impressive debut. After dropping last Monday, the song has sold 520,000 downloads in its first week.

The number is particularly meaningful since it places him at #2 in all-time first-week singles sales. Flo Rida's track "Right Round," featuring a then up-and-coming Ke$ha, has the Biebs beat, according to Hits Daily Double. Flo's track sits at #1 with 636,000 units moved. Other big sellers include the Black Eyed Peas' "Boom Boom Pow" with 465,000 in downloads (#3), and Mother Monster herself, Lady Gaga's "Born This Way" selling 447,000 (#4).

Not only are fans gobbling up the single, but his real-life girlfriend, Selena Gomez, has given the song two thumbs up. "Is it my ring tone? No. I didn't even know you could make it a ring tone," Gomez told E! News. "It is a great song."

Bieber is hardly resting on his laurels. The teen star is back in the studio working on Believe. He explained on Twitter that the album, for which "Boyfriend" is the lead single, will go there. "Here making music addressing the past and the rumors, clearing it all up in the music. Im putting it all out there on this album. #BELIEVE," he tweeted.

He also tweeted out silly videos of himself acting goofy on mock-up sets of the "Boyfriend" video, which he shot last week. In one, he stands in front of a green screen of icy land and in another he stands in front of a green screen of a fireplace.

Of course, Bieber already shared that there really will be fire and ice in the video. "The concept of this video, I mean it's not like a steady concept," he explained to MTV News on the Cali-based set in between shots. "It's not like 'Justin follows this girl to this spot.' No, it's a bunch of amazing scenes: Like a fire scene, we have an ice scene.

"It's kind of like bouncing back and forth," he said. "And then there's scenes of me and just a bunch of girl dancers, and just some great shots, great artistic shots, great shots of me smiling. It's fun."
