Patricia Arquette for Prez and Jennifer Lawrence as her VP?

That’s a showbiz likely scenario from the looks of it Friday night at the Ninth Annual Women In Film pre-Oscar Cocktail Party at Hyde Sunset Kitchen + Cocktails.

WIF’s President Cathy Schulman hosted the soiree attended by more than thirty Oscar nominees including songwriter Diane Warren, who wrote “Til It Happens To You,” plus Best Actress nominee Charlotte Rampling. ’The Danish Girl” star Alicia Vikander (a surprise guest), and “Joy” Oscar nominee Jennifer Lawrence.

Schulman, addressing the lack of women in the industry, told the A list crowd that, “Women have been leading this movement with courage that it takes to stay, stop it.”

The great Patricia Arquette– Oscar winner last year for “Boyhood”–  gave an impassioned speech and told the crowd, “Pay inequality affects 98% of women in this industry and women all over the country. Karma is coming home to roost. Black lives matter, the environment matters and ending pay inequality matters. We need to clean up our roost. “

Arquette described the other inequalities that affect women and gave a dig to the recently departed Supreme court Justice Antonin Scalia. “Scalia said that women do not have equal rights under the constitution. So just talking about pay inequality is bullshit. Millions of women need it to stop. “ Patricia urged the room to sign the petition she is sponsoring on Change.org, supporting the resurrection of the Equal Rights Amendment.

Schulman  called up surprise guest Jennifer Lawrence, who wrote an essay for Lena Dunham’s newsletter talking about her own experience with pay inequality that garnered worldwide attention. Jennifer first paid homage to Arquette. “I’m a huge fan of Patricia Arquette. I actually played a younger version of her once, and I love that she stood up. We’re starting a conversation; we’re getting a dialogue going. I didn’t know I was going to be speaking. “ Jennifer ended with a fist bump to the air, exclaiming, “equal pay for women!”

The room cheered– and that included everyone from Michelle Monaghan to Mickey Sumner, Jennifer Jason Leigh, Lake Bell, Maria Bello, Adepero Oduye, and even Oscar winning director Tom Hooper.

Lady Gaga is a professional so she absolutely went to Oscar rehearsals yesterday. Her performance tonight will be amazing, introduced by Vice President Joe Biden and featuring 50 women who are rape survivors.

But when Gaga appeared at Harvey Weinstein’s star studded private dinner at the Montage Hotel in Beverly Hills last night, she had a lot to say about the situation with Kesha and Sony Music. She said, “I got so upset thinking about Kesha I almost didn’t go to rehearsals. But of course I did, because I had to.”

Gaga, looking like a million bucks in a black and white couture outfit, showed up at the party just as it was winding down. She brought fiance Taylor Kinney and her manager Bobby Campbell, and they were all pretty excited about what they’d seen down at the Dolby Theatre.

Still, Gaga says she is in constant touch with Kesha. “I know a lot more than I can say in public right now,” she told me. “Every female artist has some kind of story of being held back by a man. And I’m thinking of all the female artists now who are trying to make it.”

Gaga did join Elton John on Saturday afternoon for live show in the Tower Records parking lot that was live streamed on aol.com. They performed Elton’s great hit “Don’t Let the Sun Go Down On Me.”

At the Weinstein party she and Taylor were immediately joined by her Oscar nominated co-writer Diane Warren, who had earlier performed “Til it Happens to You” on stage to huge applause. Her audience included Bryan Cranston, director Simon Curtis, John Legend and Chrissy Teigen, Jared Leto, Kelsey Grammer, Rooney Mara, Christoph Waltz, Andie McDowell, Kathy Narducci of “Sopranos” fame, Ron Burkle, tennis great Roger Federer, Naomi Campbell, composer Ennio Morricone, Matthew Morrison, New York Post famed gossipeuse Cindy Adams, and Derek Hough.

New hit singer Zendaya performed a smashing version of the title song from Harvey’s Broadway hit “Finding Neverland” with about a dozen back up singers. The show is about to welcome opera star and “Les Miz” vet Alfie Boe as J.M. Barrie– so here’s a scoop– Kelsey Grammer told me he’s extending his run to overlap with Boe at the end of March. Very cool.

Also part of last night’s entertainment: some selections from Weinstein’s upcoming Broadway revival of “Singin’ in the Rain.” The show was a hit in Paris last year and will arrive in New York in January 2017.

PS Chrissy Teigen is so lovely. She wore a red gown, but she is due to give birth in April to a baby girl. “Don’t you know that already?” she joked. I guess the tabloids know all this stuff. They do not have a name. John told me he’s starting to think about a new album. He and Common will present Best Song tonight — they won last year for “Glory.” John told me that when he was at rehearsals, “I felt nostalgic.” John Legend is celebrating his 12th anniversary this year as a music star. Is that possible? Time flies. And he only gets better and better!
