Katy Perry, Demi Moore, and Cindy Crawford glam up for a private pre-Oscars party in Beverly Hills

Katy Perry glammed up to attend a private pre-Oscars party in Beverly Hills on Saturday.

The 39-year-old pop star bared her shoulders in a white strapless dress, matching stilettos, and gold jewelry selected by stylist Tatiana Waterford.

Hairstylist Rick Henry blew out Katy's (born Katheryn Hudson) middle-parted raven mane and make-up artist Michael Anthony fully contoured her complexion for the industry function.

Missing from Perry's sided were her fiancée of five years - Red Right Hand action star Orlando Bloom - and their three-year-old daughter Daisy Dove Bloom.

The 13-time Grammy nominee confirmed on Jimmy Kimmel Live on February 13 that the seventh (or 22nd) season of ABC's American Idol will probably be her last in favor of traveling the world and releasing new music.

'I love Idol so much. I know. It's connected me with the heart of America. But I feel like I need to go out and feel that pulse to my own beat,' Katy - who earned $25M from American Idol in 2017 - revealed.

'It's going to be a very, very exciting year, Jimmy, for all pop star girlies. Let's just say I'm creating space for my new wingspan.'

Perry is 'really excited' to next headline the 'World Stage' of Brazilian music festival Rock in Rio, which takes place in Rio de Janeiro on September 20.

Also spotted leaving the Beverly Hills bash in a car was two-time Golden Globe nominee Demi Moore.

The Feud: Capote vs. The Swans actress easily defied her 61 years in a shimmering black Gabriela Hearst pantsuit over a white fishnet top, black Santoni heels, and Anita Ko jewelry selected by stylist Brad Goreski.

Hairstylist Dimitris Giannetos blew out Demi's signature middle-parted raven mane and make-up artist Sil Bruinsma brightened up her suspiciously wrinkle-free complexion.

Moore (born Guynes) has been hard at work in Fort Worth, TX filming her series regular role as Cami in the upcoming Paramount+ oil-pumping drama, Landman.

Taylor Sheridan and Christian Wallace's small-screen adaptation of Texas Monthly's 11-part podcast Boomtown (2019-2020) will also feature Jon Hamm, Billy Bob Thornton, and Ali Larter.

But audiences can next catch the Emmy-nominated producer in Andrew McCarthy's Brat Packer documentary Brats, which premieres this spring on Hulu.

It reunites eighties-era stars Rob Lowe, Ally Sheedy, Emilio Estevez, Lea Thompson, Jon Cryer, and Timothy Hutton.

'No one would be seen in a movie together. I hadn't seen Rob in 30 years. I hadn't seen Emilio since the premiere of St. Elmo's fire. I hadn't seen Demi,' the 61-year-old Brat author said at last month's Television Critics Tour.

'I know they have not been in touch. I'm surprised at how much affection we had for each other.'

Demi will also appear in Coralie Fargeat's feminist body horror film The Substance alongside two-time Emmy nominee Margaret Qualley.
