Hip-Hop icon LL Cool J has decided to part ways and drop out of Janet Jackson's troubled "Rock Witchu" tour.

According to the BBC, the rapper will be leaving his position as the events' opening act due to scheduling conflicts. Joined alongside the tour by Bad Boy's Donnie Klang, no replacement performer has been announced for the remaining tour dates.

This drawback is yet another issue the platinum-selling singer has to face having just been diagnosed with an unusual migraine sickness that forced her to cancel nine shows since being rushed to a hospital late last month.

As reported by, Janet was suffering from a rare form of migraine called vestibular migraine also known as migraine-associated vertigo.

The 42 year-old singer is still expected to extend the tour with more dates that have yet to be disclosed.

The "Rock Witchu" tour's next show is tonight in Michigan.
