Katy Perry announces new album titled 143

The record is available to pre-order now, according to the caption, and will be released on September 20 - a month before her 40th birthday.

It comes after the US pop singer revealed she would release her first single in two years, Woman's World, on July 11.

The 39-year-old has teased the song with an Instagram video that shows her wearing a Rosie The Riveter-inspired outfit comprised of a white and red polka dot headscarf, a bra with the US flag on it, shorts and a tool belt.

The performer, known for catchy hits including Firework and Part Of Me, last released an album in 2020 called Smile.

It arrived the same month she gave birth to her daughter Daisy Dove whom she shares with her partner, actor Orlando Bloom.
