It's official.

"If U Seek Amy" is the third song from Britney Spears' new album, Circus, to be released as a single, following "Womanizer" and the title track "Circus."

Britney's official site, which also displayed some great wedding photos from Bryan Spears' big night on New Year's Eve, first made the announcement.

Circus sold more than 505,000 copies in its first week of release. The recovering star is set to kick off a world tour March 3 in her home state of Louisiana.

As for her newest track, it's an upbeat party tune with a thinly-veiled and extremely suggestive title. It features the following (hot!) lyrics: "All of the Boys / and All of the Girls Are Beggin' to / If You Seek Amy." Get it!? Awesome.

So the dirty-minded Britney Spears may not be singing about an Amy after all. But we can think of a few Amys guys might seek (and others they might not) ...

Which Amy Would U Seek?
