The track, her first in two years, is out on July 11, with a video release the next day.

In a snippet of the track shared online she sings: “Sexy, confident.

“So intelligent. She is heaven-sent.

“So soft, so strong.”

Katy, engaged to actor Orlando Bloom, is set to release her seventh studio album this year.

She said: “It’s very bright and joyful.”

Earlier this month Katy performed at a billionaire’s pre-wedding party.

Katy performed live at the pre-wedding celebration of Anant Ambani, 29.

Anant is the youngest son of Mukesh Ambani, the richest man in Asia with an estimated net worth of $116 billion at the time of writing, according to Forbes.
