The Peas are being sued for plagiarism by Ebony Latrice Batts, known as Phoenix Phenom and Manfred Mohr, against all the members. They claim that their song "Boom Dynamite" is too much alike. Their attorney:

“My clients submitted their copyrighted song “Boom Dynamite” to Interscope Records after Interscope had shown interest in some of their music, and the Black Eyed Peas later copied the song when they wrote “Boom Boom Pow.” A simple listening of the two songs will tell you that the songs are substantially similar, and that the hooks of the two songs are virtually identical in rhythm and lyrics.” (From perezhilton.com)
