Katy Perry flashes underboob in a white bikini with armor legs to announce her new song Woman's World with a July release date

Katy Perry has let out her wild side this week it seems.

On Monday the mother-of-one shared a very sexy pinup photo that showed off her lean figure and abs in a shoot by British photographer Jack Bridgland.

The 39-year-old diva from Santa Barbara flashed her generous underboob in a white string bikini with matching briefs from DU CIEL as she posed in a studio.

And the American Idol judge also added black armor legs that made her look part robot.

The fiancée of Orlando Bloom was announcing her new song Woman's World with a July release date. 'WOMAN’S WORLD. SONG JULY 11. VIDEO JULY 12. PRE-SAVE + PRE-ORDER. GET READY TO POP OFF.'

This is the first single from her new album.

This comes after Perry said she thinks a female star should replace her on American Idol.

The 39-year-old singer previously suggested that Jelly Roll should be her replacement on the hit TV show - but on reflection, Katy now believes there should always be a female voice on the American Idol panel.

Katy - who starred on the TV show alongside Lionel Richie and Luke Bryan - told E! News: 'That would be too many men, let's be honest.

'But we love Jelly Roll, and I'd love for him to be on this show whenever it's appropriate.'

Katy also stressed that her replacement needs to be someone who is 'honest and bold, not scared of negative comments'.

What's more, the chart-topping singer suggested that she's faced more scrutiny than her male co-stars.

Katy said: 'When you have an opinion, when you're bold, when you're a female, it just happens.'

Later, Perry posted several more images from her shoot where her top barely fit her

In April, Katy actually tipped Jelly as her ideal replacement on the show.

The 'California Gurls' hitmaker told E! News at the time: 'I gotta say Jelly Roll was crazy when he came on the show.

'I was convinced at anything he said. He could run for president, he could be my pastor, I might go back to church for him. He could sell me anything.

'So I love him. And to have any of these guys plus Jelly on the show would be amazing. I love you, Jelly!'

But ultimately, Katy wants a 'truth teller' to replace her on the 'American Idol' panel.

The pop star - who quit the TV show earlier this year in order to focus on other career opportunities - said: 'I want someone that is not afraid to tell the truth in a graceful way.'
