Los Angeles: Singer Beyonce Knowles is being accused of stealing choreography on her "Formation" World Tour. According to professional dancer and personal trainer named Marlyn Ortiz, the "Run the world" singer, who kicked the tour in Miami, Florida on Wednesday, stole the routines from shows like "De La Guarda" and "El Descueve", reports aceshowbiz.com. Ortiz took to Instagram to share a clip of the alleged part which was stolen by Beyonce. She wrote alongside the video: "I'm sorry I don't bash artists! But I respect fellow creative artists... And I don't like to use social media to promote something that can be perceived as negativity... But Beyonce, you have the nerve to steal exact concepts and choreography from other real creative geniuses". "...It's ok to be inspired but at least make the effort to make it your own," she added. While Ortiz mentioned that Knowles stole the moves on "Partition" music video from Crazy Horse Paris, one commenter defended Beyonce, saying that Crazy Horse and other shows were credited in the singer's tour book.
