Guess who! Adorable throwback snap of Sydney radio star resurfaces

Known as Sydney’s radio king, he hosts a popular breakfast show on KIIS FM.

But even his biggest fans might not recognize him from this throwback photo of him as a kid in the 1970s.

The star’s radio crew shared a birthday tribute alongside a collage of photos as he celebrated his 52nd birthday.

The star in question is shock jock Kyle Sandilands, who co-hosts the wildly popular Kyle and Jackie O Show.

In one of the photos, a young Kyle is cutely dressed in what looks like his school uniform.

In the sweet photo, the radio star has styled his hair in an iconic 1970s bowl cut with short bangs as he smiles cheeky for the camera.

The collage features nine photos ranging from a sweet photo of him as a newborn to his wedding to Tegan Kynaston this year.

KIIS FM also shared three photos of Kyle and his co-host Jackie ‘O’ Henderson during their 20 years on the air together.

One photo shows Kyle in his early thirties with long limp brown hair holding a Jackie in her twenties by the waist.

The shock jock’s more recent photos are of him and his first child Otto, whom he welcomed with wife Tegan last August.

Friends and followers jumped to the comments on the Instagram post to wish Kyle a happy birthday.

One person wrote, “What a cute kid he was happy with his birthday.”

While another said, “Happy Blessed Bornday Kyle!! Age is just a numb, as long as you continue to love and live your life to the fullest with your loved ones, your inner soul and spirit will be young’.

And a third quipped, “Happy twenty-first Kyle enjoy your day.”
