Mujica later responded briefly beneath an Instagram post from the Telemundo program Al Rojo Vivo.
"Thank you so much, family," she wrote. "All I can say is that I'm devastated."
It marked her first public reaction to her son's death.
What Happened During the Barbados Trip?
Menéndez was visiting Barbados when he died. Spanish-language media reports said he had traveled to attend a sporting event.
Mujica and Osamu have since arrived in Barbados and are completing arrangements to repatriate their son's body to Miami, according to Univision.
Mujica was reportedly filming the Telemundo competition series Top Chef VIP in Colombia when she received the news. She stepped away from the production and traveled to join her family.
Has Mauro Menéndez's Cause of Death Been Confirmed?
Neither the family nor authorities in Barbados have publicly announced an official cause of death.
Some Spanish-language reports have said Menéndez was suffering from pneumonia before the trip and experienced severe breathing problems after exercising. Other reports have suggested that he suffered a heart attack.
Those accounts have not been independently confirmed by his family or local authorities. Until an official statement is released, the precise cause and circumstances of his death remain unconfirmed.
Who Was MAAHEZ?
Born in Havana, Cuba, Menéndez was the eldest child of Mujica and Osamu, her first husband. He developed an interest in music at an early age and later established himself as a DJ and electronic music producer under the professional name MAAHEZ.
He performed at clubs and events and regularly shared material related to his music career on social media. Mujica has two other children, Alejandro and Violeta.
Menéndez's death prompted condolences from members of the Spanish-language entertainment community and from viewers familiar with Mujica's television career.
The family has asked for privacy while completing arrangements and mourning the loss.
