Alejandra Guzmán is celebrating a royal moment…

The 55-year-old Mexican musician, singer, composer and actress, nicknamed “La Reina de Corazones,” has released the attitude-heavy new single “Reynísima.”

The track, which kicks off a new era in her career, is her first single as a “totally” indie artist, according to a press release.

She’s also managing her own career now.

Leaving behind any trace of pop, Guzmán places all bets on her core sound, punk rock, and delivers hard-hitting lyrics about self-governance.

“Nobody can deny my crown will continue to shine,” she declares. “My castle is in shape of a stage. I have everything because I have a star, talent is my flag, Reynísima. I am what I am because I give voice to my heart.”

The bold track comes after the Guzman’s upcoming joint tour with Mexican pop artist Fey was postponed due to “logistical” issues.
