Rock star legends Gene Simmons from KISS and ex-member David Lee Roth from Van Halen were virtually at each other's throats, which the fans saw.

One Direction and Van Halen bassist Wolfgang Van Halen have been trading insults after an incident that occurred in a hotel lobby in Birmingham, England, the Christian Post reported on Thursday, Oct. 18. Wolfgang, 21, son of Eddie Van Halen, posted on his Twitter page that the five singers from One Direction insulted him.

Van Halen postponed 31 upcoming concerts yesterday with no explanation. However, it seems that the reason behind it is not due to a feud between him and fellow band mate David Lee Roth, but because they were simply tired. A source told TMZ that the band members are "burned out" and that they want to make sure their concerts are not just routine. "They want every performance to be special," the source told TMZ.
