Jackie 'O' Henderson flaunts her slim frame as she hits the town to celebrate the release of her memoir

Jackie 'O' Henderson has turned up the heat by sharing a gallery of jaw-dropping photos to social media capturing her getting ready to hit the town to celebrate the release of her memoir.

The radio queen, 49, posted the pictures to Instagram on Tuesday night, which captured her flaunting her slim frame and flawless skin in a black ensemble.

The presenter could not wipe the smile off her face as she rocked her lean figure in a crop top paired with matching skirt which showcased her slender legs.

She completed her look with black heels and stylish sunglasses and highlighted her youthful complexion with a radiant layer of makeup.

Jackie allowed her long blonde hair to hang in loose waves around her shoulders and she looked to be in great spirits as she got ready for a big night out in Sydney.

The KIIS FM star captioned the snaps with some exciting words.

Off to do a little celebrating with friends. Thanks for the support today, love you guys,' she wrote to her adoring fans. 

It comes after Jackie announced the profits of her memoir The Whole Truth will be donated to charity.

The media personality recently came under fire after revealing on The Kyle and Jackie O Show that she secretly checked into the Betty Ford Clinic for drug and alcohol addiction in November 2022.

Many criticised the radio personality for using an overseas facility favoured by the rich and famous, while thousands of Australians struggle to afford local rehabilitation services. 

On Monday, Jackie took to Instagram to share that she took on board the comments and would be donating her book's profits to a worthy cause.

In the post, she wrote a long message to her fans, saying she had been 'deeply moved by the thousands of messages' she had received from people 'unable to afford rehab'. 

Jackie went on to acknowledge that not every person who struggles with addiction would have the same opportunity.

'Which is why, all my profits from my book, which is on sale tomorrow, will be donated to Odyssey House Drug and Alcohol Rehabilitation Centre,' she continued. 

'Odyssey House provides life-changing support to individuals seeking treatment but who are struggling financially...the work they do is powerful, important and transformative.'

The radio star made the stunning admission about her addiction issues during a tearful conversation with her co-host Kyle Sandilands on their KIIS FM radio show last Thursday morning.

Jackie revealed that at the height of her addiction she was consuming up to 12 Stilnox sleeping pills and 24 Panadeine Forte tablets daily, often with alcohol.
