Radar the fourth single from Circus

Now, finally, after weeks of changing single names, the official one has been confirmed. Britney's fourth single from Circus will be Radar.

The song was first written and recorded for her 2007 Blackout album, and even appeared on that, and was supposed to be a single in June 2008, but this plan was cancelled. Next, it appeared on Circus as a bonus track, which surprised a lot of people.

Than now, the song is finally confirmed to be the next single. A big bummer, since the song wasn't even made for Circus! Everyone has heard it now already, it has already been in the charts, so I don't think it will be a big hit.
