Sir Elton John and David Furnish are fuming over Madonna’s Golden Globes win.

After John predicted on the red carpet that Madonna had “no [bleep]ing chance of winning,” he was stone-faced when Madge — at her first Globes appearance in 14 years — triumphed for best original song Sunday night.

Her tune “Masterpiece,” from “W.E.,” beat John’s “Hello, Hello” from “Gnomeo and Juliet.” After the win, Furnish posted on Facebook: “Madonna. Best song???? [bleep] off!!!”

After her acceptance speech Madonna delivered in a bizarre English accent, Furnish told us: “I think it was a fluke . . . When this happens you have to question the integrity of the awards. Did Madonna get the Golden Globe because she attended the awards and agreed be a presenter?”

He added, “Can you sing Madonna’s song? Can you hum it? It’s a song nobody has heard, from a film few have seen. The award should have gone to Mary J. Blige or Elton. I like Madonna’s music, but not her movies. She should stick to what she is good at.”

But Madonna was glowing at CAA’s Sunset Tower Hotel after-party, both for her win and turning the tables on Globes host Ricky Gervais by saying, “Why don’t you come over here and do something about it,” after Gervais’ crack about her being “like a virgin.”

At the star-studded CAA bash, Angelina Jolie relaxed in a seating area as Brad Pitt ditched his cane and caught up with George Clooney [photo: opposite page], who was with gal pal Stacey Kiebler, and Leonardo DiCaprio and supermodel girlfriend Erin Heatherton.

Bradley Cooper chatted until nearly 2 a.m. with Emma Stone, while Mila Kunis and Olivia Munn sat nearby. Later, Cameron Diaz — hanging with Maroon 5’s Adam Levine and DiCaprio on a terrace — was smoking something more fragrant-smeling than a cigarette.

A source close to Madonna said, “[“W.E.”] has not officially opened . . . so [it is] accurate that many people haven’t seen it yet. There was no deal made about an award for her attending.”
