Finally, a role Lindsay Lohan can carry off — heroically overcompensated plaintiff.

The 23-year-old actress has launched a $100 million (U.S.) lawsuit against discount brokerage eTrade, according to the New York Post.

At issue is an eTrade TV ad that first aired during last month’s Super Bowl. In the spot, entitled ‘Girlfriend’, a pair of CGI’d babies have a webchat about a missed date the night before.

The boy says he was busy working on his portfolio. The suspicious girl wonders, “And that milkaholic Lindsay wasn’t over?”

“Lindsay?” the boy says.

Another girl baby enters the frame.

“Milk-a-what?” she asks.

Ba-doom-boom.

Of course, Lohan has had well-publicized issues with drug abuse. She’s rehabbed at least twice. Since falling in stages from her Hollywood perch beginning six years ago, Lohan is best known for her erratic lifestyle.

She made cringing headlines again this week by failing to turn up for a Paris show by fashion house Ungaro. Until her no-show, everyone still believed that Lohan was Ungaro’s “artistic adviser.” Apparently not.

A day later, she makes more headlines with this nine-figure suit.

“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,” Stephanie Ovadia, Lohan’s lawyer, told the Post.

Ovadia suggested that Lohan has elevated ‘Lindsay’ to the same sort of one-off recognition status as ‘Madonna’ or ‘Cher’. If that’s so, she’s not helping the brand.

In 2004, when a thriving Lohan starred in her breakout film, Mean Girls, ‘Lindsay’ was the 240th most popular name for girls born in the U.S.

In 2008, after Lohan had suffered a steady series of slips, it was 380th.

The rehab effect on naming is still an under-researched area of study. Courtney is now the 269th most popular girl’s name. Britney is 689th.

For their part, the agency behind the ad told the Post that Lindsay was named after a member of their account team.
