She made worldwide headlines this week after she was spotted kissing Oscar winner Sean Penn on a Hawaiian beach on Wednesday.

But just who is Leila George, the 24-year-old lover of Oscar winner Penn, 56?

The Australian-born blonde is a burgeoning actress with an A-list pedigree, born to Emmy nominees Greta Scacchi - who at 56 is the same age as her new man - and Vincent D'Onofrio, 57.

Rising star: Leila George is the beautiful Australian actress and rumoured new girlfriend of Oscar winner Sean Penn

Scacchi is best known for her performances in Broken Trail, Rasputin, and the Australian classic Looking For Alibrandi, while fans will recognise D'Onofrio from Law & Order: Criminal Intent, Daredevil, and Jurassic World. 

Unlike her established parents, Leila's acting career is only just beginning, with the ingénue recently making her screen debut in the Lifetime TV movie Mother, May I Sleep with Danger? alongside James Franco and Tori Spelling.

Prior to that, the thespian honed her craft on the stage and in prestigious acting schools across the globe.

Pucker up! The 24-year-old made headlines across the globe after she was spotted kissing Sean Penn, 56, in Hawaii on Wednesday 

Age ain't nothin' but a number! The unlikely lovers share an age difference of 32 years 

At 19, she completed a course at The Australian Film School in Sydney, before spending two years studying in the Lee Strasberg Institute in New York.

Little else is known about Leila, with the blonde beauty keeping a relatively low-profile until her tryst with Penn went public this week.

In steamy pictures of the pair, the 56-year-old Milk actor can be seen passionately cupping Leila's neck and face as he kisses the bikini-clad actress in the Oahu surf.

Famous family: Leila's mother is Australian screen legend Greta Scacchi, who starred in Looking For Alibrandi and has been nominated for multiple Emmy awards

Big daddy: The rising star's father is Vincent D'Onofrio, best known for Law & Order: Criminal Intent, Daredevil, and Jurassic World

Good genes: The blonde beauty is no stranger to showcasing her impeccable physique on social media 

Oahu is a location close to Penn's heart, with People reporting that the actor owns a beachfront home there. 

He also spent time there with ex-fiancée Charlize Theron.

While Leila's dating history is unknown, Penn's love life is common knowledge, with the actor romancing countless A-list starlets over the years.

Hollywood: The skilled star recently made the move from stage to screen in the Tori Spelling Lifetime TV movie 'Mother, May I Sleep With Danger?'

Mixing business with pleasure? Sean and Leila recently recorded an audiobook together

Some of his best known wives and lovers include Madonna, Robin Wright, Scarlett Johansson, Jewel, and many others.

Sean is known for enjoying the company of younger women, so it's no surprise that at 56, he's only one year younger than Leila's 57-year-old father. 

Furthermore, Leila is just one year younger than Penn's daughter, Dylan.
