Anne Hathaway hilariously fooled the entire Ellen audience into doing a fake "healing ritual".

Anne Hathaway has zero time for the “wellness” trends of Hollywood.

You see, many celebrities love to shower their adoring fans with wellness advice, but Anne Hathaway isn’t having a bar of it.

The 36-year-old actress hilariously proved the point that not all celebrity-endorsed wellness is legitimate, when she encouraged the entire audience of The Ellen Show to practise “citrus healing”, a form of meditation she had completely made up, on Wednesday.

Appearing to promote her new film Serenity, the The Devil Wears Prada actress began by telling the audience a fake story about how she had encountered a family of hippies in California over the holidays, and that they had taught her a new… ritual.

She then encouraged the audience to reach under their seats and pull out the mandarin they’d been gifted and asked them to peel it.

Things were getting weird.

The Ocean’s 8 actress continued to discuss a “book” called Citrus Healing at length.

“It was all the ways that you can incorporate citrus into your life to raise your health… Aromatherapy, you can use the peels for cleaning products, and one of the things was how to incorporate citrus into your meditation practice,” she said of the “book”.

Hathaway then got to the punch line, and asked her audience to hold the peeled fruit to their mouths and breathe deeply. Which they all did.

She followed up the bizarre ritual by asking the audience how they felt afterwards.

"Do you guys feel a little bit better? Feel good?" she asked the audience.

Then she let them in on her little secret.

"That’s impossible, I made the whole thing up."

Ellen, with the fresh fruit still in her mouth, appeared shocked, leading Hathaway to explain the point she was making.

"The takeaway of this is: Do not put something in your mouth just because a celebrity tells you to. You are free to throw your clementine (mandarin) at me now," she told the audience.

During the appearance, the actress also revealed that she intends on being sober until her infant son is 18.

In the interview, she admitted she made the decision after a trip with her Serenity co-star, Matthew McConaughey, and his wife, Camila Alves, where they spent much time patronising rum bars on the island of Mauritius.

After one night in particular, Hathaway couldn’t exactly remember the details of her experience the next morning – yet she still had to meet with the Serenity director.... hungover.

“We drank the night away, and then I had to go to a meeting with Steven Knight, our director, the next day, and I was just kinda – have you guys ever had to do a meeting hungover?” the actor asked the Ellen audience.

“I was just kinda stumbling in with one eye open and I was trying to convince him about certain things about my character.”

The actor took full responsibility for her actions, but admitted she had difficulty ‘keeping up’ with her friends.

“They’re both cool, and I just can’t drink as much as them,” Hathaway said of her co-star and his wife.

It was after that night that Hathaway made the decision she wouldn’t drink for the next two decades. ¯\_(ツ)_/¯
