The band went on tour over spring and summer 2010 to promote the release of "Epic". With Jeffree Star they recorded three songs for that album. However, the collaboration was short-lived since during the "Looking Hot & Dangerous Tour", Star accused Vanity of being a pedophile and a predator, claiming to have witnessed suspect behavior. Star later chose to go back on his accusations and sweep what he claimed to have seen under the rug and later was featured on their 2014 single "Poison Apple", from the album "Bitchcraft". As with the previous conflict with Garrett, the three singles featuring Jeffree's vocals were re-recorded with vocals by Jayyvon, and the original tracks were not featured on the final album. In October 2010, the album "Epic" charted No. 5 on the dance/electronic Billboard chart. The band headlined the Epic Tour and the Epic Tour Part II in support of the album. Even before the release of "Epic", recording began for Blood on the Dance Floor's fourth album, "All the Rage!!". The duo collaborated with several artists for the album, including Lady Nogrady, JJ Demon, and Nick Nasty. The album was preceded by several singles to promote the release, including "Bewitched", "Yo Ho", and "P.L.U.R." The band embarked on Warped Tour 2011 in June 2011, and released the album while on tour. A music video for their hit single from the album, "Bewitched", featured Nicole "Lady" Nogrady, who later said that she felt disrespected by the band during production of the album as well as on the music video, and found herself having to confront the band directly in order for her name to appear on the credits of her work with them. The song was subsequently performed by other female vocalists in place of Nogrady at live shows, and was re-recorded with vocals by Haley Rose for their 2013 acoustic album "Blood Unplugged". The album peaked at No. 13 on the "Billboard" Top Electronic Albums chart. At the end of 2011, the duo headlined the All the Rage Tour and was planning the 'Tis the Season to be Killing Tour. In celebration of BOTDF's fourth anniversary, a digital compilation album entitled "The Legend of Blood on the Dance Floor" was set to be released on Halloween. The compilation's release date was pushed back, originally planned to be released as a CD, it was released as a soundcloud playlist instead.
