CHRISTINA AGUILERA - AGUILERA'S EXTRAORDINARY TRADEMARK BATTLE

Saucy diva CHRISTINA AGUILERA has filed an ambitious list of bizarre trademark products with America's Patent and Trademark Office.

The sexy singer is seeking to protect 450 products and brands including sex toys, contact lenses, crayons, deodorants, badminton sets, ski wear, underwear and modeling clay.

Her trademark lawyer, ROD S. BERMAN says, "The goodwill associated with her name could be used to brand a huge variety of goods and services. She's a personality that is relevant not only to the higher teens and 20s, but also to kids."
