Heather Graham, 54, almost spills out of her strapless gown as she attends Night Before the Oscars party... after posing in a bikini

Hollywood veteran Heather Graham, 54, almost spilled out of her strapless black gown on Saturday.

The Hangover actress attended the star-studded MPTF's 22nd Annual Night Before event. It is one of the top pre-Oscar parties in town.

The event took place at the Fox Studio Lot in Los Angeles.

The dress was quite the number as it had a sheer lace panel on the midsection. She added strappy gold heels and a small black shoulder bag with a gold chain strap. 

Her long blonde hair was worn down over her bare shoulders.

Also at the event were musician and model Paris Jackson and Barbie actress America Ferrara who posed with her husband Ryan Piers.

Also at the event were sisters Kyle Richards and Kathy Hilton. They have feuded in the past but seem to be getting along better these days. They are both stars of The Real Housewives Of Beverly Hills. 

Eva Longoria looked very slender in this long black gown with a slit up one leg as she added pointy heels with a rhinestone ankle strap.

Zooey Deschanel wore a plunging black gown with a mermaid finish. Helen Hunt kept it cocktail party chic with a flirty black dress and strappy high heels.

Jodie Foster wore a red suit as she held onto a small red handbag while posing with partner Alexandra Hedison who opted for a black outfit with black nails.

The Motion Picture & Television Fund raised more than $4.3 million at its 22nd annual star-studded benefit on Saturday night.

The exclusive event was co-chaired by Sterling K. Brown and Ryan Michelle Bathé, America Ferrera and Ryan Piers-Williams, Jodie Foster and Paul Giamatti.

Funds raised from the event will be used to support industry members and their families who benefit from MPTF’s charitable programs and services, such as financial assistance, crisis counseling, caregiving support and residency on the Wasserman Campus in Woodland Hills, which now serves as 'home' to many television and film veterans. During the recent work stoppages, MPTF received over 13,000 calls for aid and provided more than $8 million in charitable financial assistance.

This comes after Graham showed off her impossibly slender figure this week while on a yoga retreat in Mexico.

The Drugstore Cowboys actress wore a chocolate brown string bikini while in new images she shared to Instagram.

The cover girl from Milwaukee, Wisconsin had a flat tummy with abs and sculpted legs as she looked to be toned to perfection.

The 54-year-old star has said in the past she looks so youthful because she likes to sleep a lot. Often she gets as much as 12 hours of shut-eye a day.

And the looker, who has worked since she was a teen, also said she meditates twice a day as it centers her and makes her relax.

'So grateful I got to go on a yoga retreat and meditate looking at the ocean with @soukofrima_ and @mjmasala @souk.studio. Me gusta ❤️,' she said in her caption.

She is also a big yoga fan which she started doing when she worked on Twin Peaks prequel Fire Walk With Me in 1992.

The star was with her boyfriend John de Neufville, 47. 

In February, she stole the spotlight at the 39th Annual Santa Barbara International Film Festival Closing Night.

The stunning star looked incredible in a stylish red gown as she arrived at the Arlignton Theatre gala, which included the world premiere of her film Chosen Family.

The dramedy was written and directed by the actress, who also stars in it alongside Julia Stiles, Andrea Savage, Ella Grace Helton and John Brotherton.

She effortlessly commanded attention at the event in her bold gown, showcasing a plunging neckline and a strategically placed cut-out design that highlighted her sculpted abs. 

Opting for minimal makeup, Heather let her natural beauty take center stage as she posed alongside her co-stars, Ella and John.

Also at the event were sisters Kyle Richards and Kathy Hilton. They have feuded in the past but seem to be getting along better these days. They are both stars of The Real Housewives Of Beverly Hills

In Chosen Family, Heather takes on the role of Ann, a yoga teacher on a quest for inner peace amidst her chaotic family dynamics and a less-than-ideal dating life.

Despite her struggles, Ann grapples with an inability to say no, constantly finding herself entangled in others' problems. 

As she endeavors to mend her fractured relationship with her sister Clio (Stiles), Ann leans on her friends Roz (Savage), Max (Thomas Lennon), and Frances (Odessa Rae) for support.

'I’m so excited to be making my dream project with an amazing team,' Graham previously said in a statement. 

'In a male-dominated industry, we love supporting women,' producers Chad A. Verdi and Michelle Verdi told The Hollywood Reporter.

'Heather’s drive, writing, directing and starring in this film has been wonderful to witness.'

Heather's big night at the annual festival comes a week after Robert Downey Jr. was recognized with the esteemed Maltin Modern Master Award at the Arlington Theatre.

Downey Jr. - whose searing performance as Lewis Strauss in Oppenheimer is gaining Oscar buzz - was also joined by superstar pals Rob Lowe, David Duchovny, Natasha Leggero, Chelsea Peretti and more. 

Cillian Murphy - who played nuclear physicist J. Robert Oppenheimer in Christopher Nolan's blockbuster - beamed with pride as he posed with the guest of honor. 

The Modern Master Award is the highest honor presented by SBIFF, according to its website. 

'Established in 1995, it was created to honor an individual who has enriched our culture through accomplishments in the motion picture industry,' reads the statement.

The award was re-named the Maltin Modern Master Award in 2015 in honor of long-time SBIFF moderator and renowned film critic Leonard Maltin. 

Past winners included Jamie Lee Curtis Javier Bardem, Nicole Kidman, Bill Murray Brad Pitt, Glenn Close, Gary Oldman and Denzel Washington.
