Someone has teased Jessica Simpson's hair to dizzying new heights!

Over the weekend, the singer's publicist posted a startling TwitPic of Simpson, 30, with her blonde locks (and maybe some extensions) fluffed up in the style of an 18th century noblewoman.

Reportedly prepping for a magazine photo shoot, Simpson -- currently engaged to ex-NFL pro Eric Johnson -- wore a white robe and a sultry expression in the pic.

"Hey Jessica Simpson," the caption red, "Nice new 'do for 2011."

The star was in NYC last week for a "MAJOR work week" for her fashion collection, Simpson Tweeted.

"Can't wait for y'all to see the new JS Collection goodies! Inspired in 2011."
