Monica passes out after her performance in Houston...

Concerned concertgoers watched anxiously as legendary R&B singer Monica fainted after performing a gig in Houston, alongside her co-headliners Joe and K. Michelle. She was defiant and tried her best to power through but something was clearly off. It was obvious to everyone that the usually robust powerhouse was vocally defeated, and all was not well. 

Monica has previously opened up about her health issues in the past which included her experiences dealing with a heart condition, endometriosis and high blood pressure. She even revealed she has been hospitalized multiple times for migraines. Scary. Prayers up for her recovery.
