Phoebe Tonkin shows off her huge diamond ring as she attends the 2024 WWD Honors Awards in first sighting since announcing her engagement to her secret boyfriend

Phoebe Tonkin surprised fans when she announced her engagement to her secret boyfriend Bernard Lagrange this week.

And on Tuesday, the Boy Swallows Universe star proudly showed off her huge diamond ring as she attended the 2024 WWD Honors Awards in New York.

The Australian actress, 35, ensured her sparkler was the main focus as she placed her hand on her dress while posing on the red carpet.

In her first sighting since the news, she looked elegant in a long red pleated dress which featured draped sleeves.

Slicking her dark locks back behind her ears, Phoebe enhanced her stunning features with a flawless base and a bold red lip.

A pair of silver earrings completed her look as the glamorous movie star worked all her best angles on the red carpet.

Phoebe's red carpet appearance came just one day after she announced she is set to tie to the knot with Bernard.

The actress shared the exciting news to Instagram alongside a series of loved-up photos with her fiancé.

In one image, Phoebe wore a white dress as she sat on Bernard's lap and wrapped her arms around him as they shared a kiss.

Her stunning oval diamond engagement ring was on full display during the intimate moment.

Phoebe also posted another photo as she gently touched Bernard's face in a car and revealed her new ring.

'Film back from the summer of love. Special first photo by my friend @mark_bauch,' she captioned the images.

Her fans took to the comments to express their shock, with one writing: 'Are you engaged? WHAT!'

'Hard launch like no other,' a second person commented. 'IS THAT AN ENGAGEMENT RING?!' another questioned.

Little is known about Bernard, but he is believed to be an art dealer, and it is unclear when they started dating, with fans previously unaware of their romance.

Prior to her romance with Bernard, Phoebe was linked to American rocker, Alex Greenwald.

She confirmed their romance on Instagram in 2020 by sharing a picture of the pair kissing while wearing face masks.

It's unclear when the relationship ended.

Phoebe also previously dated Paul Wesley but they split in 2017 after four years together.
