According to reports from TMZ, Dutch singer Thea Van Siejaen is suing RZA over unpaid royalties for work the two did together from 2004 through 2011. Her vocals were used on his track "Baby Boy," which was featured in Jet Li's film Unleashed, as well as 13 other songs.

She claims she was initially afraid to ask for the money for fear of being pushed out of the music industry. It will be interesting to see how far this case gets.
