They are both known for their impressive radio careers, high-profile breakups and platinum blonde locks.
So it was no surprise to see Jackie ‘O’ Henderson, 48, buddying up to gal pal Carrie Bickmore, 42, during a afternoon cruise on Saturday.
Joined by a group of friends, the group spent the day sipping champagne on a private yacht as they sailed on Sydney Harbour, a day after Jackie’s interview with Gwyneth Paltrow at the Besties event at Aware Super Theatre.
Jackie flaunted her dramatic 18kg slim down in a strapless pink sundress that featured ruffle detailing.
Styling her hair in loose waves, the bronzed blonde completed her look with a pair of see-through heels, black sunglasses and a white handbag.
At times, she was seen clutching a beige sherpa jumper and her mobile phone.
Meanwhile, Carrie oozed elegance in a white cut-out midi dress and matching flat sandals.
The former Project host added a pair of tortoise-shell sunglasses, white statement earrings and wooden bead bracelets.
She also carried a brown felt tote bag and a woollen jacket that matched her frock.
Like Jackie, Carrie wore her flaxen hair down in loose waves.
Jackie and Carrie looked like they were having a ball on the vessel as they joked with friends, posed for selfies and soaked up the springtime sunshine.
Among the guest list was Jackie’s best friend and Besties business partner Gemma O’Neill.
Also spotted aboard was KIIS FM newsreader Brooklyn Ross and his partner Damien Dirienzo, as well as Jackie’s former KIIS FM and friend Simon Greally, Sea FM content producer Kim Czosnek, publicist Jane Negline and entrepreneur Lucy Ormonde.
During the cruise, Jackie took to Instagram with a photo of herself and Carrie posing with the iconic Sydney Opera House behind them.
Fans immediately remarked how similar the two women looked.
‘Wow you and @bickmorecarrie could literally pass as sisters right now,’ one commented.
‘Same thought here,’ another agreed with one more person commenting under the image, ‘Uncanny.’
Indeed, Jackie and Carrie have more than their good looks in common – they are both single after each suffering high profile divorces.
Jackie has been married twice, to DJ ‘Ugly’ Phil O’Neil in the late 90s and to photographer Lee Henderson from 2003 to 2018.
The former couple share custody of 12-year-old daughter Kitty.
Carrie meanwhile announced her divorce from TV producer Chris Walker in January following an 11-year marriage.
‘It’s with immense sadness that Chris and I have decided to separate,’ she wrote in a statement on Instagram at the time.
‘While this is a tough time, our focus is on parenting, loving and supporting our three children Ollie, Evie and Addie with everything that we’ve got.
‘They are doing great. We won’t be making any further comment.’
The former couple are now co-parenting their three children, Ollie, 15, Evie, seven, and Adelaide, four.
Carrie is rumoured to be secretly dating her radio co-host Tommy Little, however she has remained mum on her relationship status.
