The world revolves around Lindsay.

Lindsay Lohan is suing the financial company E-Trade, insisting that a boyfriend-stealing, “milkaholic” baby in its latest commercial — who happens to be named Lindsay — was modeled after her. And she wants $100 million for her pain and suffering, The Post has learned.

The actress filed a lawsuit yesterday in Nassau County Supreme Court over the commercial that debuted during the Super Bowl this year.

The ad — part of a series starring babies who play the stock market — features a boy apologizing to his girlfriend via video chat for not calling her the night before.

“And that milkaholic Lindsay wasn’t over?” the baby girl asks him suspiciously.

“Lindsay?” the boy replies, just before a baby girl sticks her head into the frame and slurs, “Milk-a-what?”

Lohan’s lawyer, Stephanie Ovadia, said the actress has the same single-name recognition as Oprah or Madonna.

“Many celebrities are known by one name only, and E-Trade is using that knowledge to profit,” Ovadia said.

“They used the name Lindsay,” Ovadia said. “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.”

Ovadia wants an injunction to force the spot off the air, and the Lindsay camp wants every last copy of the commercial.

Chris Brown, a spokesman for Grey Group, which produced the spot, is throwing cold milk on the controversy, saying it “just used a popular baby name that happened to be the name of someone on the account team.”

Ovadia said E-Trade has violated Lohan’s rights under New York state civil-rights law and used her “name and characterization” in business without paying her or getting her approval.

The lawyer said that since the spot was seen by hundreds of millions of people watching the Super Bowl and Winter Olympics finals, the firm has garnered great profits.

She says Lohan is owed $50 million in exemplary damages, plus another $50 million in compensatory damages.

E-Trade could not be reached for comment.
