Jackie O Henderson celebrated her 49th birthday on Wednesday.

And to mark the special occasion, her KIIS 1065 team surprised the radio star with an extravagant custom birthday cake.

The blonde beauty looked remarkably fresh-faced as she posed near her incredible yacht-shaped cake, which was topped with a fondant character wearing a bikini that resembled Jackie. 

In a video, the radio queen revealed she was spending the day with a friend before going for dinner and heading to English singer RAYE’s, concert.

‘I’m so excited… I think she’s amazing. I love her music,’ she said.

She also revealed she will be celebrating her birthday over the weekend with a boat party and explained why she had decided to do something big for her 49th.

‘I just feel like every single year of my life I have ignored birthdays and never wanted to do a party,’ she said.

‘I just don’t like doing it and I thought “You know what? Why not! Like who cares how old you are or whether it’s a milestone, I’m going to throw a big party on a boat.” So, it’s the first time I’ve ever thrown a party for myself.’

‘I feel like this year, I just want to live life, you know?… I feel like last year I did a lot of learning about myself and that sounds so cliché… but I actually have, and now this is the year to reap the rewards. It’ll be a fun year; I want to make it as fun as possible!’

She was recently forced to deny that Ozempic is behind her spectacular slim down.

Ozempic, an appetite suppressant previously used to treat Diabetes type II, has seen an increase in prescriptions for obesity in recent years and is now used by many celebrities to keep a trim figure.

Jackie has always insisted she achieved her weight loss by going on WW (Weight Watchers), which she was an official ambassador for.
