Two Virginia songwriters are suing Justin Bieber and Usher for $10 million for copyright infringement.

Devin Copeland and Mareio Overton claim Bieber's song "Somebody to Love" contains numerous lyrical and stylistic similarities to the song they wrote in 2008 by the same name.

The duo filed a lawsuit Thursday in federal court in Norfolk, Virginia, claiming that numerous producers conspired to copy their song. A message left Monday with a law firm representing Bieber was not immediately returned.

The lawsuit says Copeland and Overton provided a copy of their song to musical promoters, who in turn provided it to representatives of Usher.

The lawsuit says the song performed by Bieber peaked at No. 15 on the U.S. Billboard Hot 100 chart in 2010 and was certified platinum.
