Anne Hathaway revealed Taylor Swift's influence over her new film Mother Mary as well as the 'magical' thing the singer did for her.

The 43-year-old actress, who has also been busy promoting The Devil Wears Prada 2, opened up about the topic during an appearance on The Late Show With Stephen Colbert on Wednesday.

At one point, the talk show host showed a scene from the upcoming psychological thriller as Hathaway performed a pop song on stage for a cheering crowd.

'I understand... you mention Taylor Swift,' Colbert told the star. 'But how did she influence this?' 

Hathaway replied, 'I mean, she was kind of like an angel that I felt like was over our heads all the time.' 

She went on to explain that the director David Lowry was a big fan of the Grammy winner and had taken inspiration from Swift's Reputation tour for the movie. 

'And I was influenced by her tour film Miss Americana and how vulnerable she just let herself be,' Hathaway added.

'And kind of showing a pop star that we are so used to seeing like so in their power and so polished. You know, what happens when they are kind of in between moments when they're having a moment of metamorphosis?' 

The actress said that it could be 'so painful' before noting the difficulty of being a public person 'trying to figure things out in the spotlight.' 

The Princess Diaries star further gushed, 'I was already a fan but after that I had so much empathy for her and her humanity and of course her talent.' 

Hathaway then recalled a special moment she had with the Bad Blood hitmaker amid her Eras Tour. 

She had been filming Mother Mary in Germany and Swift's tour stop in the country coincided with when she was also there. 

The actress said the performer 'makes the audience feel so loved and she made me feel so loved. And I'm like, "Oh my God, Annie, you're so cute. You think Taylor Swift is waving at you. You are so adorable."'

And the experience became even more memorable for Hathaway when she was given a note from Swift herself.  

'Somebody tapped me on the shoulder and they said Taylor wants you to have this and I went, what is happening?'

The actress continued, 'It was a note where Taylor said, "I'm so happy you're here, I'm going to be enthusiastically waving at you." 

'I was like, "Oh my God! She is so magical! She did the thing. I was right, I am special,"' she jokingly added. 

Mother Mary is set to hit theaters on April 17 and also stars Michaela Coel, Hunter Schafer, Kaia Gerber, Atheena Frizzell, Jessica Brown Findlay, FKA Twigs and Alba Baptista. 

The premise is: 'Long-buried wounds rise to the surface when iconic pop star Mother Mary reunites with her estranged best friend and former costume designer, Sam Anselm, on the eve of her comeback performance,' per IMDB. 

Hathaway also discussed how she had reached out to singer Charli XCX in regards t her leading role in the movie. 

Original songs by Charlie XCX as well as FKA Twigs and Jack Antonoff are featured in the psychological drama. 

'The person that I spoke to was Charli... I wanted to talk to her about the music, she wrote such amazing music that I was going to perform,' the actress recently told People. 

'But I also just had a lot of questions for her about what her life was like, what the experience of being a pop star was.' 

Earlier on Wednesday, Hathaway turned heads as she made a grand arrival to The Late Show in New York City. 

She put on a leggy display wearing a black minidress that had velvet material around the shoulders and arms. 

Large gold buttons were placed on the front while intricate details were embroidered on the pockets. 

Her brunette locks were parted in the middle and effortlessly flowed down past her shoulders in light waves. 

The star additionally slipped into a pair of black tights and closed-toed, black platform heels. 

Hathaway accessorized the chic look with a gold necklace as well as a few rings and fashionable shades. 

She flashed a cheerful smile while also holding a black purse for a finishing touch.

Along with the A24 film Mother Mary, the actress will appear in the anticipated sequel The Devil Wears Prada 2. 

The movie is slated to hit theaters on May 1 - 20 years after the first movie premiered in 2006. 

The sequel also stars Meryl Streep, Stanley Tucci, Emily Blunt, Justin Theroux, Kenneth Branagh and Patrick Brammall. 

'It's so massive,' Hathaway said of the film during a recent appearance on the Today show. 

'I really feel like everybody's delivering something that people could really use right now and I'm just so proud and thrilled to be in it.'
