Julie Bishop cuddles with alleged new boyfriend Luke Hepworth at Qantas 100th Gala Dinner

Julie Bishop snuggled up to her alleged new boyfriend Luke Hepworth as she attended the 100th Qantas Gala Dinner in Sydney on Friday night.

The former foreign secretary, 66, stuns in a semi-sheer maxi dress in muted reds, blues and browns.

She added a pair of dangling statement earrings and carried a metal clutch purse.

The politician wore her blonde bob in soft waves and opted for a clean makeup look with a pint of lipstick.

Luke, on the other hand, looked dapper in a structured black suit paired with a shirt and bow tie in the same dark tone.

The handsome “adventure philanthropist” is the CEO of a multinational PSA company.

It is Bishop’s third red carpet appearance with the handsome businessman, although he has denied the two are dating.

She went through a painful split from her partner of eight years, David Panton, last year.
