Jackie attended the event with her best friend Gemma O’Neill.

The media powerhouse ensured all eyes were on her in a form-fitting pink dress which showcased her enviable figure and youthful appearance.

She wore her blonde locks in loose waves around her shoulders and added fiery red lipstick for the occasion.

At one point, Jackie thought a selfie was in order to commemorate the moment.

Elsewhere, Elle exuded elegance in a chic black double-breasted blazer and matching turtleneck.

She allowed her blonde hair to cascade around her shoulders and added a subtle layer of makeup to accentuate her striking facial features.

Jackie will also record her KIIS breakfast show from Melbourne on Monday.

The Sydney native and her co-host Kyle Sandilands signed a record-breaking $200million 10-year deal live on-air late last year – keeping them on the airwaves until 2034.

The historic new radio deal will see them expand to Melbourne.
