It's actually a music group formed in 2010, with the same name as the one used in anime.

Here's the complete detail: Love Live! (ラブライブ! Rabu Raibu!) School Idol Project is a Japanese multimedia project co-developed by ASCII Media Works' Dengeki G's Magazine, music label Lantis and anime studio Sunrise. The project launched in the August 2010 issue of Dengeki G's Magazine, and went on to produce music CDs, anime music videos and a manga adaptation. An anime television series produced by Sunrise and directed by Takahiko Kyōgoku began airing in Japan on January 6, 2013. The project revolves around a group of fictional school girls who become idols to save their school from shutting down. ''sourced from http://en.wikipedia.org/wiki/Love_Live! ''

And there is another suprising fact:

Every songs they've released so far, all is stated in the manga which this series is adapted from. Also, for the real music group, each of the member are not known by their actual name, but by the character names they are representing. For instance, Emi Nitta, who representing Kousaka Honoka, will known as Honoka both in the anime and the albums they released, and not as Nitta.
