The Beautiful Monsters Tour was a North American concert tour co-headlined by American rock bands Hole and Marilyn Manson. Launched in support of each band's respective third full-length studio LPs, 1998's Celebrity Skin and Mechanical Animals, the tour was planned to run from February 28, 1999 until April 27, with 37 shows confirmed. However, due to a highly publicized altercation between the bands' respective lead vocalists, the tour only visited arenas until March 14, for a total of 9 shows before Hole withdrew from the bill. The tour garnered a large amount of media attention and was billed by MTV as a "potentially volatile mix" due to the public feud between each band's outspoken vocalist.
