Australia's most eligible bachelorette Francesca Packer-Barham is off the market

She is Australia's most eligible young bachelorette, but it looks like James Packer's niece, Francesca Packer-Barham may be off the market.

According to The Daily Telegraph, the 22-year-old heiress is said to be dating Englishman Charlie Watson, after the duo were spotted putting on an amorous display at Sydney's Gold Dinner, last week.

The eldest grandchild of Kerry Packer is understood to have met 34-year-old Charlie in the UK, while studying interior design at Inchbald College and living in the affluent suburb of Knightsbridge.

And it looks like Francesca is keen to share their new romance with the world. On Saturday, the brunette posted a snap to Instagram showing the pair looking every bit cosy while attending the charity event.

Both looked dressed for the black tie occasion -- Francesca sporting a floor-length black gown -- while Charlie wore a tailored suit jacket, white shirt, and black dress shoes.

"When Mr Watson comes to town…" She captioned the black and white pic.
