This news was personally confirmed by her talent manager, Ogie Diaz who announced the said issue through his official Twitter account when he replied on one of Soberano's fan.
The Fan [Liezel Manalo @iamlie29] said, "@ogiediaz sana gumawa ng sariling album si Liza,,ganda ng boses sayang kung d ilalabas."
Diaz then replies, "Meron po. Inihahanda na."
Seeing how fan notice how Soberano sings on some episode of Forevermore where she is part of a band 'The Time Machine' will clear everyones doubt on how good she sings.
If you watch her performance with Enrique Gil in the finale of 'Your Face sounds Familiar' where the two of them sung the One Direction's "Kiss You," her voice was really pleasant to hear eventhough she suffered a wardrobe malfunction.
