AceShowbiz - Katy Perry gathered her band in a bathroom to give an impromptu performance of her latest single "Small Talk" on Thursday night, August 22.

In a post shared to Instagram, the 34-year-old danced around the "medium sized bathroom" wearing a pink feathered dress and matching heels, as she belted out the upbeat number.

"Potty jams, featuring Small Talk," she said at the start of the clip, before turning to face the camera as she stood next to a urinal.

She then went on to sing the track, walking around the room to show her two keyboard players, one sitting on a urinal and another standing, a guitarist on a toilet, and her drummer on an acoustic box, on one side of the bathroom.

The "Firework" star's backing singers were on the other side of the room, with one even playing a third keyboard.

The star also played up to the camera during the performance, flashing her stunning engagement ring from beau Orlando Bloom as she sang the line, "And isn't it awkward I got a new somebody".

As the song concluded, one of her guitarists, who was seated on a toilet, flushed, as she exclaimed: "That's the s**t!".

Katy previously filmed a bathroom session for her last single "Never Really Over", but she recorded the video herself in the bathroom mirror with a small group from her band behind her.

"Small Talk" is the second single to be taken from Katy's upcoming sixth studio album.
