Kyle’s radio rival Ben Fordham also joined the festivities on board.

Kyle and Tegan made a dramatic entrance together on the superyacht by arriving on a speedboat and then proceeding to jump on-board the yacht together.

According to The Daily Telegraph on Saturday, Kyle gave guests a dress code for the evening, which was to “add a touch of gold.”

Kyle and Tegan, 35, looked incredibly stylish as they arrived, with Tegan wearing a shimmering gold sequined mini dress.

Kyle looked sleek in a suit, shades and bright red scarf.

Jackie O, 46, went all out for her look, wearing a gold blazer dress.

The Kyle and Jackie O Show Instagram page shared a shot of Kyle and Jackie O together with the caption, “Mum and Dad at Kyle’s 50th.”

They also shared a photo of the star’s birthday cake, which was a lavish three-tiered black fondant cake with a huge red crown sitting on top. The words “King Kyle” were embossed on the front of the cake, the same of which was written on the side of the yacht.

Behind the cake was also a gold balloon display and light numbers displaying the big ‘50.’

Surprisingly, two of Kyle’s long-term friends Sophie Monk and Karl Stefanovic were nowhere to be seen.

However the party didn’t end on the yacht.

Kyle had plans for the party to rage on into the evening, with The Daily Telegraph capturing photos of his attendees arriving at his home later that day.

John Ibrahim was absent from the official yacht, but the former King of the Cross was amongst the second wave of guests who made their way to Sandilands’ Edgecliffe Rd mansion on Saturday night.

He arrived with his girlfriend Sarah Budge just after 7pm and was seen leaving with a blonde friend around 9pm.

Onlookers told The Sunday Telegraph that: “It was actually quite an intimate vibe”.

“It was a lot of family and real friends. It was all surprisingly very genuine.”
