Jackie ‘O’ Henderson and bestie Pip Edwards enjoy a festive boat party on Sydney Harbour with their glamorous friends

Jackie ‘O’ Henderson and Pip Edwards proved they can party at the weekend as the best friends let loose at a festive boat gathering.

The PE Nation co-founder, 44, shared snaps from the wild party to her Instagram account on Monday, showing off her fit abs as she posed in a black bikini.

The fashion designer showed off her other glamorous friends and cuddled up with her KIIS FM radio star Jackie on Sydney Harbour.

The 49-year-old media personality opted for a more casual outfit during her day out on the boat.

Jackie swept her blonde locks back into a stylish updo and pulled her slim figure into an Amalfi Beach Club T-shirt and denim shorts.

Meanwhile, Pip put her incredible bikini body on display as she cast her frame in a two-piece that left little to the imagination.

In an attempt at modesty, accessorizing with a matching sheer sarong, the socialite hid her eyes behind dark designer glasses.

As the sun began to beat down on the bronzed beauty and her glamorous friends, Pip practiced sun safety by donning a black straw cowboy hat.

Jackie and Pip’s fun day out on a boat comes after the duo stepped out as each other’s dates to the GQ Men of the Year Awards in Sydney.

The PE Nation founder cut a dashing figure in a striking all-black outfit as she entered the exclusive event with her radio queen best friend Jackie.

She looked radiant in a black blazer teamed with matching trousers and heels as she and Jackie led the arrival at the converted White Bay Power Station.

Pip and Jackie were the ultimate star couple of the evening, turning heads as they confidently strutted their stuff among their A-list friends.

Jackie put on an equally glamorous display as she showed off her incredible figure in a striking black backless dress.

She gave herself a few extra inches in a pair of heels as she strutted her stuff and worked the angles for the camera, showing off her toned frame.

Jackie, who is currently single, wore a chunky gold bracelet and wore her golden locks falling in loose waves over her shoulders.

Pip, who recently debuted a new romance with Joshua Clapp, and Jackie have become close friends in recent months and often spend time together.

Pip recently revealed how she supported Jackie after the radio presenter admitted she was struggling with drug and alcohol addiction.

Jackie spoke for the first time last month about her years-long battle with addiction in her recently released memoir, The Whole Truth.

Speaking about Jackie’s courage in telling her story, Pip said she was inspired by her friend’s honesty.

“I think it was extremely healing for her and it was time for her to stand in her truth. It’s nothing to be ashamed of. And to all the critics: fuck off. Sorry,’ said Pip.

“The night Jackie released the story on the radio, I went to her house to be with her and give her a big hug.”

Pip said the women are “spiritually aligned” and share an incredibly close friendship.

Jackie spent 28 days in renowned rehab, The Betty Ford Center, in November 2022 after struggling with addiction during the Covid lockdown.

At the height of her addiction, she was taking about 10-12 Stilnox/Ambien sleeping pills and 24 Panadeine Forte painkillers per day.

After overcoming her addiction issues, Jackie recently marked two years of sobriety on November 14 – just weeks after publicly speaking out about her addiction.

She told Ny Breaking Australia how she celebrated the milestone by going out for dinner with her loved ones.
