Model Simone Holtznagel’s new romance with celebrity love

Sydney’s hottest single is officially off the market, with model Simone Holtznagel spotted out and about with a new celebrity beau.

TWO of Sydney’s hottest singles are an item.

Confidential can reveal top model Simone Holtznagel is dating celebrity personal trainer Jono Castano.

The pair have kept their romance on the down low after meeting through the industry.

Castano actually trained Holtznagel several years ago, when he was married to business partner, Amy Castano.

The new couple were spotted together at an event marking Hennessy’s global partnership with America’s National Basketball Assocation (NBA).

“Jono and Sim have been spending a lot of time together,” a friend told Confidential. “They enjoy each others company a lot.”

Holtznagel is one of our top international modelling exports, having done campaigns with the likes of Guess as well as appearing on the cover of Playboy.

She rose to fame as a teenager on Australia’s Next Top Model.

Castano meanwhile owns his Acero gym in Kensington and has trained the likes of Rita Ora, Rebel Wilson, Michael Clarke and Candice Warner.

He and Amy split last year but remain close friends and business partners.
