From an article about a Los Angeles belly dancer Sahira Badr. I really doubt this woman was "mobbed" at any Stevie Nicks' concert.

Sahirah is theatrical. When not dancing, she plays World of Warcraft, dresses up as Narcissa Malfoy at Harry Potter conventions, attends Medieval events in full garb and enjoys hard-edged alternative Goth music. In addition, her uncanny resemblance to the famous Fleetwood Mac singer, get her mobbed at Stevie Nicks’ concerts. She currently studies with classical Egyptian dancer, Soraya, and attends as many workshops as she can.
