B2K’s Raz B and his wife Mona Li faced the tragic loss of their 3-month-old son, Astro Monte. The Fulton County Medical Examiner revealed that the cause of death was “asphyxia due to airway obstruction,” and it was ruled as an accidental occurrence.
TMZ initially reported the news, with PEOPLE confirming the details. The unfortunate event took place in September. The family publicist, David Robinson, issued a heartfelt statement expressing the couple’s sorrow over the unexpected passing of their son. They requested privacy as they navigate this challenging period. The statement read, “It is with heavy hearts that we announce the unexpected passing of Astro Monte Thornton, beloved son of Mona and De’Mario ‘Raz B’ Thornton of the R&B supergroup B2K.”
Raz B, whose real name is De’Mario Monte Thornton, and Mona Li share two children. Alongside Astro, the couple has a son named Versai Carter, born in October 2024. Mona Li also has an older daughter from a prior relationship. Earlier in April, Mona had shared her joy of being nine months pregnant on Instagram. She expressed immense pride in her husband as he completed the Boys 4 Life Tour, emphasizing the significance of witnessing his success both as her partner and from the audience.
In May, the couple joyfully announced the birth of Astro in a joint Instagram post. They posed with their son Versai and Mona’s daughter. The caption reflected their happiness and anticipation, stating, “I always wanted to take a real family picture with my own family… and finally, God made a way. Right now we’re at the hospital getting ready to welcome our newest addition, Astro, another baby boy to the Thornton family.”
Raz B praised his wife, calling her strength through motherhood a significant blessing. The couple expressed gratitude as their family and legacy continue to grow.
