Megan Fox was spotted riding solo and not wearing her engagement ring at the Vanity Fair Oscar Party on Sunday.

The 36-year-old actress was seen without her fiancé Machine Gun Kelly, 32 – amid their troubled romance – as she partied with fellow A-listers at the bash celebrating Hollywood’s biggest night.

For the lavish event held at the Wallis Annenberg Center in Beverly Hills, the Jennifer’s Body star put on a busty display in a plunging black gown.

The Transformers alum highlighted her ample assets in the daring velvet dress as she enjoyed the party.

She looked dazzling in a chandelier diamond necklace but, most noticeably, was spotted without the double engagement ring personally designed by her beau.

For her solo night out, the Hope & Faith vet opted for a Miss Sohee couture gown that featured delicate scalloped edging around the bust.

To finish off the look, she donned a pair of Piferi platform heels and accessorized with a stunning, diamond statement necklace.

The mother-of-three wore her now-ginger red tresses in loose waves over her shoulders.

She put on a glamorous display in a sultry, smokey eye, rosy pink blush, and a dusty mauve pout.

At the extravagant event, she posed with Billie Eilish as well as Zelie Timothy and Tyrese Gibson while working the room.

Not present at the event was the rapper – who she has been with for around three years.

The couple sparked breakup rumors last month when Fox uploaded a cryptic Instagram post about ‘dishonesty’ and scrubbed her social media of any pictures with the hitmaker – also known as Colson Baker.

Shortly after the couple had been spotted together at a Super Bowl party together, Megan wrote in the caption of an Instagram post: ‘You can taste the dishonesty / it’s all over your breath’.

The lyrics – from Beyonce’s 2016 track Pray You Catch Me – alongside a sultry selfie and a photo of burning letters seemed to suggest trouble in paradise.

Shortly after, the Till Death star deactivated her Instagram page before quickly resurfacing to shut down rumors of a split and insisted that no cheating had occurred in their relationship.

A source revealed to People that while the engagement hasn’t been ‘officially called off’, Megan did remove her ring and has been clearly seen without the token.

‘They have had issues in the past, but things seem pretty serious this time,’ the insider revealed.

At the end of February, Page Six reported that the lovebirds had been having daily couples therapy sessions over Zoom.

According to People, an insider close to the couple said they are ‘still not in a good place’ even after slamming rumors of him being unfaithful.

The pair previously met on the set of Midnight In The Switchgrass and had starred alongside each other in the 2021 thriller film.

Fox and MGK dated for over one year before they got engaged January 2022.

At the Oscars, Everything Everywhere All at Once was the big winner on Sunday night – taking home seven awards.

The American absurdist action comedy-drama film was the biggest winner of the night at the event featuring a star-studded red carpet as it earned Best Picture, Best Director, Best Actress, Best Supporting Actor, Best Supporting Actress, Best Editing, and Best Original screenplay at the gala event held at Dolby Theater in Hollywood.

The movie’s stars Michelle Yeoh, Jamie Lee Curtis and Ke Huy Quan, took home the Leading Actress and Supporting Actress and Actor awards respectively.

In her acceptance speech, Michelle hailed her win as a ‘beacon of hope and possibilities’ for Asian people and urged those watching at home to ‘dream big’.

She said: ‘For all the little boys and girls who look like me watching tonight. This is the beacon of hope and possibilities. This is proof to dream big and dreams do come true.

‘Ladies, don’t let anybody tell you you are past your prime. Never give up…

‘Thank you to the Academy, this is history in the making, thank you.’

The film beat out quite the field including: All Quiet on the Western Front, Avatar: The Way of Water, The Banshees of Inisherin, Elvis, The Fabelmans, TÁR, Top Gun: Maverick, Triangle of Sadness, and Women Talking.

Meanwhile, Best Actor in a Leading Role went to Brendan Fraser, who was tearful as he picked up his prize for his work on The Whale.

He said: ‘So this is what the multiverse looks like. I thank the Academy for this honour and our studio A24 for making such a bold film.

‘I’m grateful to Darren Aronofsky for throwing me a creative lifeline and hauling me aboard the good ship ‘The Whale’. It was written by Samuel D. Hunter who is our lighthouse.’

German war movie All Quiet on the Western Front also had a successful evening, taking home four of the prizes it was nominated for, Best International Feature Film, Best Cinematography, Best Original Score, and Best Production Design.

This year’s Academy Awards – which were hosted by Jimmy Kimmel – saw all the nominated tracks for Best Original Song performed, but the accolade went to Naatu Naatu from RRR.
