Diana Ross approves of Lee Daniels’ ‘United States vs. Billie Holiday’

Lee Daniels’ latest film, “The United States vs. Billie Holiday” has gotten a ringing endorsement from someone whose opinion matters most: Diana Ross.

The superstar singer, known for hits such as “Ain’t No Mountain High Enough,” “I’m Coming Out” and “Love Hangover,” made her feature film acting debut as the groundbreaking jazz singer in 1972 1/4 u2032s “Lady Sings The Blues.”

The Motown diva also scored a Golden Globe award and an Academy Award nomination for her depiction of the drug-addicted, glamorous music trailblazer behind self-penned tunes such as “God Bless the Child,” “Now or Never,” “Fine and Mellow” and “Don’t Explain.”

For Daniels’ latest cinematic foray, Grammy Award-nominated singer/songwriter Andra Day also makes her feature film debut as Holiday in a multi-layered narrative that tells the not-so-glamorized side of her tragic but impactful legacy.

Ross’ youngest son, Evan Ross, also stars in the movie which focuses on the U.S. government’s campaign to destroy Holiday as her anti-lynching ballad “Strange Fruit” frazzled the J. Edgar Hoover-run FBI.

The 32-year-old actor said his mom approves of the film — and not just because he’s in it.

“She loved it,” Ross told Variety columnist Mark Malkin. “She loves Lee, and she thought it was cinematically amazing. She thought the performances were amazing.”

With his role as young FBI agent Sam Williams, the 32-year-old actor — seen in films such as “ATL” and “Moo-Slim” — plays a pivotal role in bringing down the iconic singer and songwriter, all under the direction of the corrupt and racist Harry J. Anslinger (played by Garrett Hedlund).

Although Daniels digs much deeper and took a less-romanticized approached to the Suzan-Lori Parks-scripted Billie Holiday story, Evan Ross thinks her life should be explored on the big screen again.

“It’s so important for the story to be told again, plus it brings more attention to ‘Lady Sings the Blues,’” he shared. “People can watch that movie again, too. It made me first want to learn about Billie Holiday. I think the same thing is going to happen now.”

Evan Ross, also an alum of Daniels’ star-studded Fox drama “Star,” revealed that the “Rise Up” singer took a totally method approach to the role.

“She doesn’t smoke in her life. She doesn’t drink,” he shared. “She was in character all the time. And so by the end of it, I was like, ‘Did I make best friends with Billie Holiday?’ because she was so in there. I even worried because she was so deep in. But she really pulled it off.”

Unlike “Lady Sings the Blues,” Daniels film is a darker and more explicit affair, presenting many dimensions of Holiday’s love life (with male and female partners) but most notably federal agent Jimmy Fletcher — with whom she had a dark and stormy relationship.

“Moonlight” star Trevante Rhodes stars as Fletcher in the film, which also include performances by Tyler James Williams, Rob Morgan, Tone Bell, Natasha Lyonne, Miss Lawrence, Leslie Jordan and Da’Vine Joy Randolph.

Some 49 years after his mom launched her successful acting career embodying Holiday in a Berry Gordy-produced and Suzanne de Passe-scripted classic, Ross told Yahoo!’s Kevin Polowy that he was “happy to be part of something so powerful and amazing.”

“The United States vs. Billie Holiday” premieres Feb. 26 on Hulu.
