The 36-year-old singer arrived to the studio in Los Angeles wearing a comfy beige cashmere sweater dress and sneakers, with her dog Nugget in tow. 

Carrying a colorful robe and some slides, the mother-of-one looked ready to go as she headed into wardrobe for her transformation.

Katy emerged in a deep red vinyl wrap dress and PVC over-thee-knee boots and carried a coffee with her. 

During Sunday’s episode of the show, Katy joked about cosmetic work she’s had done on her face.

After watching 21-year-old caretaker Willie sing an original song called Never Be Alone, then do a soaring version of Beyoncé’s I Was Here, Katy was impressed.

‘Every time, I get chills,’ she marveled. ‘Tonight, I got chills in places on my face that I thought I had frozen. Okay? You brought the chills back. It was a Lazarus moment on my face.

‘You have that connection to the next realm,’ she told the Douglas, Georgia, resident. ‘And it’s been so beautiful to see you come in—kind of shy, with this big voice, not so sure—and you are stepping into your power and you are walking in the light.

Speaking to People ahead of her performance, she said: ‘[Being pregnant] was the first time I had ever experienced nurses because I’d never been to the hospital. 

‘I had no idea how to surrender, but you definitely have to surrender after you have a baby. I didn’t know what I was surrendering into – I just did, and I was like, “Wow, these nurses are literally angels”. 

‘I really thought it was amazing that there were actually such incredible selfless angels out there that are working in healthcare. It was so positive. They’ve been under a lot of intense stress.’
