What flat iron was nicole richie using in the 1st season of the simple life?

I dont know but I just bought one from Sallys beauty supply and its the best in the world...you might want to try it, its called....Helen of Troy Jewel Tools...it gets to 450 in heat, it gets hot in seconds...your going to have to spend a pretty peny on it, $60, but trust me its worth it. Ive already spent money on cheap Walgreen and Target type that cost $20 and I wish I hadnt done that...might as well invest in a good one and be done with it.
