Following a weekend of celebration for his two big wins at the American Music Awards, Usher has found himself in a legal battle over the song 'Caught Up,' which is alleged to have been stolen from another writer. According to a lawsuit filed by Wadena Pyatt and Bang Hitz Publishing in the Eastern District of New York, Usher plagiarized the song.

Pyatt, who was once an artist on Alicia Keys' MBK Entertainment Label, claims to have written a party version of the song in 2002. Pyatt signed a contract with the label in 2003, and had plans to use the song on her debut album, and is seeking damages and any profits made from the single. The song, which appeared on Usher's 2005 album 'Confessions,' lists Ryan Toby, Andre Harris, Vidal Davis and Jason Boyd as writers. The Dre & Vidal-produced track was released as the fifth and final single off the album, peaking at No. 8 on Billboard's Hot 100 singles charts.

This isn't the first time that Pyatt has sued a well-known musician for copyright infringement. In 2005, she filed a lawsuit against Wyclef Jean, claiming she did not get credit for co-writing the song 'Two Wrongs.' Although the case was dismissed, Pyatt has filed an appeal to the ruling.

Usher and Keys, have yet to release a statement regarding the matter.
