What is radar brintey spears?

I'm sorry, but Radar is a song by Britney Spears, not a person. "Radar" is a dance-pop song from Britney Spears' sixth studio album, Circus, released in 2008. The song was released as a promotional single in Europe, Australia, and some parts of Asia. It peaked at number 88 on the US Billboard Hot 100 chart. The song's lyrics talk about being in love and feeling like someone is always watching you like radar. It has a catchy chorus and upbeat production typical of Spears' music.
