Lindsay Lohan broke down after seeing an E*Trade ad featuring a "milkaholic" baby girl which she claims mocks her.

"She said, 'Mommy, help me. This is wrong. How can they do this?'" Dina Lohan tells the New York Post.

The ad, which debuted during the Super Bowl, features a baby boy apologizing to his girlfriend for not calling her the night before because he was on E*Trade. "And that milkaholic Lindsay wasn't over?" the baby girl then suspiciously asks.

Dina said Lindsay -- who filed a $100 million lawsuit Monday, demanding that E*Trade stop running the ad and turn over all copies to her -- became "extremely upset" at the ad because she felt it poked fun at her wild past.

Said Dina, "They're little babies doing this, mocking another child who's just trying to survive Hollywood, basically."

Dina added that the ad was clearly aimed at her daughter because unlike other stars, "Everyone knows Lindsay, like Cher or Madonna."

An E*Trade spokeswoman has declined to comment on the suit, but Dina said it is warranted.

"I'm just basically glad I took a stand," she said of the "horrible" and "mean" ad. "I'm not going to let them do this to us anymore."
