Katy Perry appeared topless in a new image shared on social media on Wednesday morning.

The Santa Barbara was sharing big news: she showed her album cover, announced it was titled 143 and revealed the release date is September 20. 143 is a code for 'I love you,' often used in the early 1990s in messages sent on pagers.

This new collection of songs is coming out just before she turns 40-years-old on October 25.

The pop siren had on a shiny clear acrylic tank top over her chest that made her look nude as she added a see through iridescent skirt. 

Her long black hair was worn down and she was beautifully made up with long lashes and a mauve lip. Behind her was a red and white celestial storm that made her look lost in the cosmos as her arms out made her resemble an angel.

'I set out to create a bold, exuberant, celebratory dance-pop album with the symbolic 143 numerical expression of love as a throughline message,' said Perry in a statement. 

Perry has been presenting a sexier image and a leaner figure with her new album.

The 143 album will be led by the single Woman’s World, which Perry will release on Thursday at 7 p.m. ET. The video for Woman's World will come out on July 12. 

On Tuesday, the Hot N Cold hitmaker gave her fans a glimpse of her Woman's World music video. 

She was dressed as Rosie the Riveter in the 14-second clip for the single, which appears to be an intended empowerment anthem.

She put on a busty display in a bedazzled string bikini top in the shape of stars and covered with a red, white and blue, American flag-inspired design.

The songstress also sported denim micro shorts with a rhinestone toolbelt slung low on her hips. 

Alongside a group of backup dancers, she showed off her moves while stomping around in over-the-knee, lace-up boots. 

The 13-time Grammy nominee looked like a proper pin-up doll with dark hair styled in a retro updo and her bangs in 1940s victory rolls.

She tied a red bandana with white polkadots around her chic bun. 

In the same clip, she also rocked a double-denim look as she threw on a zip-up, short-sleeved top. 

'Celebrate,' she sang in the teaser. 'We ain't going away.' 

The clip showed scenes of the scantily-clad dancing provocatively as well as putting bedazzled power tools to work.

She was also seen pouring a bottle of 'Whiskey for Women' into her mouth but missing as the liquid trailed down her body.

The brunette bombshell has been promoting her upcoming release since late last month. 

Her upcoming music has been a topic of controversy as it was previously revealed that Woman's World was produced by Dr. Luke, who Kesha, 37, famously accused of sexual assault a decade ago.

Perry previously worked with the Kemosabe Records founder, 50, for many of her past hits, including I Kissed A Girl and Teenage Dream.

The music producer was embroiled in a highly publicized legal battle against the TiK ToK singer, in which he was accused of sexual, physical, and emotional abuse.

Kesha also alleged that Perry was also a victim – a claim she denied and said was false. 

One year after the pair settled, Dr. Luke, whose real name is Łukasz Gottwald, has been listed as a co-producer on Perry's upcoming single — prompting fury from fans who questioned how Perry can reconnect with the songwriter to promote female empowerment.

A source told DailyMail.com that Perry 'isn't bothered' despite her fans' concerns.

'She understands she is controversial by working with Dr. Luke again, but they work so well together, and they have such a rapport with each other that she knows him in a different way than others might,' the insider stated.

'Her relationship with Dr. Luke is an important one,' the source continued. 'So to have worked with him again is something she isn't bothered about, even though plenty of fans are.'

It was added: 'She is scared as the music world today can be fickle, with artists here one minute and disappearing the next — but she has thrived before.'
