Katy Perry got into a Cinderella costume on Sunday night’s American Idol episode.

And on Tuesday the diva revealed that she will be selling the glᴀss slippers she wore on Idol for her line, the Katy Perry Collection.

The Firework singer, 39, was dresses as the Disney princess from the original 1950 animated film.

Katy – whose daughter Daisy Dove attended Sunday’s taping of American Idol – posted the pH๏τo carousel to promote the new shoe.

She captioned it: ‘Shoesday was so magical it started on Sunday,’ tagging her brand @katyperrycollections.

In the post, she shares three of the shoes in her collection which all resemble the coveted golden slipper, though two of them are tinted pink and brown, respectively.

The golden slipper shoe is available in pink, sepia and black and according to the website copy are made for ‘magical nights out.’ They are on sale for $65.

On Sunday, the I Kissed a Girl hitmaker also wore her Cinderella costume, albeit in a bit more magical way.

She first appeared in Cinderella’s work clothes but as she spun around, she turned into the princess-to-be in the pale blue dress and black choker.

Sunday was also Mother’s Day and Katy made sure to get tributes out to both her mother and her daughter Daisy Dove.

‘Today I told my mother that the day I realized how much she loved me is the day I had my own daughter, Daisy Dove… there is nothing like a Mother’s love… never take it for granted,’ she wrote.

‘Happy Mother’s Day to all the mothers and caretakers — any way you come ♥️’

Perry and Bloom first met in 2016 and after taking a break in 2017, the pair got together for good less than a year later.

They got engaged on Valentine’s Day in 2019 and welcomed Daisy in 2020.

Plans for their wedding were put on hold during the Covid-19 shutdown, but with some spare time on her hands, the California Gurls singer could walk down the aisle sooner rather than later.
