If you double-cross Madonna, there’s a chance she will call you out in front of a packed arena.
The venerable pop star, 57, shared a personal story of betrayal Thursday on stage in the Philippines during the Manila stop on her “Rebel Heart” tour.
“Once I had a Filipino trainer — this beautiful, beautiful girl. She was gorgeous and very talented as a trainer,” Madonna told a sold-out crowd of 20,000 people. “But she f—-d my boyfriend, so I fired her.”
The fit femme fatale in question is likely Madge’s longtime trainer Nicole Winhoffer, a source told Page Six.
Winhoffer — who describes herself as “born in NYC to a Filipino mother and German father” on her website — worked with the “Ray of Light” singer for five years before parting ways in 2014 and helped the singer launch eight branded gyms worldwide as creative director of Hard Candy Fitness.
“Nicole has been teaching her own method in NYC and acts as if she left Madonna on her own to be an entrepreneur,” continued the source.
In addition to training sessions, the exercise guru is currently a Global Ambassador for Stella McCartney’s line of Adidas workout gear and was once a backup dancer for Shakira.
“In this case, it was not a happy ending,” continued Madonna in her onstage revelation. “I know I sound like I’m cynical and I don’t believe in romance and that I think everybody is backstabbing.”
A source confirms Winhoffer did sleep with the same man as Madge, but says it was before he ever dated the pop legend.
During the time the two worked together, Madonna dated dancers Timor Steffens and Brahim Zaibat, both three decades younger than the “Like A Virgin” singer.
Madonna reportedly split from Steffens, 28, in the middle of a European vacation in 2014.
Requests for comment from reps for Madonna and Winhoffer were not immediately returned.
