Police are investigating the sudden death of French singer Barbara Weldens.

According to BBC, the rising star was on stage in Goudron, France, when she apparently went into cardiac arrest.

Her cause of death remains unconfirmed. Though the publication notes that officials did not want to speculate, rumors have been swirling.

BBC noted that early reports suggest electrocution is to blame.

A spokesperson told Europe 1 they "will see in the next weeks if a reevaluation" is needed. They also plan to determine whether an electrical malfunction occurred and, if so, why.

In a statement, the organizers behind the Pic d'Or prize, which the 35-year-old won in 2016, addressed her death.

"It was with great emotion that we learned this morning of the death of Barbara Weldens, our Pic d'Or 2016 at a concert last night in Gourdon in the Lot, obviously electrocuted," the statement read.

"Our team is deeply disturbed by the brutal disappearance of the artist who had appeared on the stage of the Theater des Nouveaux on May 20th, during our last edition. A radiant woman, full of energy and talented, and of course we think of all her family and her loved ones," it continued.

Weldens released her first album, "Le Grand H de l'Homme," on February 3.

A bio on Weldens' website suggests she grew up around circuses. When she wasn't learning to juggle, do acrobatics or swing on the trapeze, she was writing poems, playing piano and singing.

Her dreams of being a musician were temporarily put on hold in adulthood, but took off full force in 2011 when she began working with the Théâtre de Pierres.

Weldens won several awards during her lifetime, including first prize in the Jacques Brel Young Talent competition in 2016.
