The retired supermodel, 59, reportedly began dating the billionaire businessman in September (15), after being introduced to one another by the mogul's sister and niece.

They are said to have enjoyed dates in California and New York, and on Saturday, Jerry and Rupert made their first public appearance together as they headed to the sporting extravaganza at Twickenham Stadium, wearing matching Team Australia scarves to cheer on the 84 year old's native country as the Wallabies faced off against New Zealand's All Blacks.

They have yet to comment on the relationship, but the pair happily posed for pictures together as it headed into the venue to take its seats in a private suite. Rupert was also photographed planting a big kiss on a smiling Jerry's cheek after his team scored their second try. However, Australia eventually lost out to New Zealand 17 to 34 to win the Rugby World Cup.

They weren't the only famous faces in the crowd - Australian pop star Kylie Minogue and British royals Prince William and Prince Harry were also among the thousands who turned out for the final.

Jerry famously split from Rolling Stones Frontman Mick in 1999, after it was revealed he had fathered a lovechild with Brazilian model Luciana Morad. The former couple, which began dating in 1977, shares four children.

Rupert parted ways from his third wife, Wendi Deng, in 2013.
