Although the KIIS FM presenter joked that it would be a “watered-down party”, it looks like they didn’t skimp on the $25,000 jungle-themed birthday party.

Kyle and his wife Tegan, celebrity friends, dressed in joyful rags, arrived at his Bellevue Hill mansion to celebrate baby Otto’s birthday.

The shocking athlete even organized a party for the day, where 24 children and 38 adults were invited to celebrate their youth.

“It’s only $25,000,” Kyle said at the time. “It’s a watered down party.”

Following the birth of son Otto last August, Kyle tied the knot in a no-cost ceremony at the Swifts’ mansion in Darling Point, Sydney.

Kyle reportedly spent $1 million on the event, which was attended by the likes of Prime Minister Anthony Albanese and leading showbiz figures.
