Simone’s younger model sister Madeline Holtznagel was also onboard the yacht.

She is dating pub baron Justin Hemmes who treated the Sydney-based siblings and their friends to a fancy meal at his Newport restaurant Bert’s Bar and Brasserie, for Madeline’s 26th birthday.

The party then continued at Hemmes’ $60 million Vaucluse mansion.
