Transgender singer Sephy Francisco once again impressed international audiences when she auditioned on the X-Factor UK, Saturday, September 15 (UK time).

The call center agent, who rose to fame after singing in both a female and male voice on ABS-CBN's local franchise of I Can See Your Voice, surprised everyone when he sang "The Prayer."

Simon Cowell, Louis Tomlinson, Ayda Field and Robbie Williams were all in awe when Sephy flawlessly performed the song originally done by Celine Dion and Andrea Bocelli.

Simon even said on her jaw-dropping performance: "I’ve never judged a duo who’s one person! This is incredible. I save money, you make more money!"

Just this year, Sephy also made the Philippines proud when she was invited to join the original franchise of I Can See Your Voice in South Korea.

In an exclusive interview with PUSH a few months ago, Sephy shared her how it was singing for an international audience.

“It’s life-changing. It’s the very first time I traveled out of the country. And to be able to know the Korean culture, the food, the people, it’s all worth it. I feel so blessed to experience this once in a lifetime opportunity,” she stated.
