An actress who hawked stool softeners and laxative capsules on TV is suing because she was made redundant by a bobblehead.

Phoebe Jonas — a k a “the Phillips Lady” in ads for Phillips’ Colon Health capsules and other Bayer digestive products — says in Manhattan court papers that her former employer replaced her with a wobbly-headed figurine of herself in commercials to avoid paying her.

Jonas’ suit notes that she helped peddle Bayer products from June 2016 until her contract ended this past March.

Then, “Bayer began airing ads of a Bobble Head that looks identical to” Jonas, according to her suit.

“Bayer created the Bobble Head replica to avoid renegotiating the right to continue to use plaintiff’s likeness,” the suit charges.

“At no point did plaintiff ever give Bayer consent, permission and/or authority to create and/or air the Bobble Head video portraying her likeness on the internet, television commercials or any other form of media.”

Bayer has ignored the actress’ demands for compensation, the court papers add.

“It’s one thing to not pay — it’s another thing to turn an actor into a bobblehead to try and not pay,” Jonas’ lawyer, Steven Mintz, told The Post on Monday.

“This lawsuit is going to give Bayer a headache,” he quipped of the company, which is known for its aspirin.

A clip of Bayer’s “Cubicle” ad, which features Jonas the bobblehead, can be found on the company’s website.

In the commercial, the bobblehead asks two female co-workers in a cubicle, “Anyone ever have occasional constipation, diarrhea, gas or bloating?”

“She does,” the co-workers answer in unison, pointing across their desks at each other.

Without skipping a beat, the bobblehead replies, “Help defend against those digestive issues. Take Phillips’ Colon Health probiotic caps daily with three types of good bacteria.”

Jonas, who has also appeared on “Law & Order” and “The Nanny Diaries,” is suing for $500,000 and to stop Bayer from using the bobblehead in commercials.

Chris Loder, spokesman for the pharmaceutical company, said, “This preposterous complaint is without merit, and we intend to fight these baseless claims.”
