Khloé Kardashian hits back at critic who says she looks like an 'alien' in new commercial

The back-and-forth came after the reality star appeared to debut yet another new look in a recent commercial for Nurtec, a prescription medicine used to treat migraines.

"You have every right to block/mute me," she continued. "I am trying to help many out there who suffer in silence. I R [sic] completely entitled to your opinions. Just as I am mine." Kardashian also took aim at the critic’s Twitter bio, writing, "I don’t think you should refer to yourself as a feminist if you are attacking a woman unprovoked."
