Lindsey Loahn is suing E*trade for using her "Name" in this ad...Here is the publicists report

Many celebrities are known by one name only, and E-Trade is using that knowledge to profit. They used the name Lindsay. They're using her name as a parody of her life. Why didn't they use the name Susan? This is a subliminal message. Everybody's talking about it and saying it's Lindsay Lohan."
