Jackie O Henderson doesn’t look like this anymore! Radio host stuns fans as she debuts a very different hairstyle

She is one of Australia’s most recognizable faces.

But on Wednesday, Jackie O Henderson looked different as she showed off her new hair transformation.

The radio presenter, 49, had her locks chopped before arriving to host KIIS FM’s Kyle and Jackie O show.

Jackie O ditched her normally long, straight blonde locks for a voluminous, curly look.

She showed off her new hairstyle as she informed her co-host Kyle Sandilands about the surprise she had organized for him ahead of their radio launch in Melbourne.

“I have a surprise for you today,” she said.

“You know how you said last year that you really wanted the Kyle and Jackie O bus to come along when we go to Melbourne and events?”

Kyle admitted, “This is after we lost the limo, I wanted to take it one step further.”

“Well, it’s coming this morning,” Jackie O said.

The radio star’s new hairstyle comes after she recently lost a whopping 18kg.

The mother-of-one recently spoke about her new diet on The Kyle and Jackie O Show and said she often skips breakfast, a practice known as intermittent fasting.

She also avoids carbohydrates and satisfies her hunger throughout the day by snacking on pre-cut pieces of steak.

“I cook the steak and cut it up, and if I’m hungry I just have a little piece of steak,” Jackie said.

She resists wasting too many calories at lunch, choosing to eat just “three small pieces of steak” and a few Vietnamese rice paper rolls with fish and cabbage.

Her co-host Kyle Sandilands was shocked by her small portion size and told her, “A dog would eat more!”

For dinner, Jackie usually eats vegetables and a protein such as chicken or red meat.

In between meals, Jackie treats herself to smoothies and Starbucks Frappuccinos, a type of blended iced coffee drink.
