Bobby Brown's wife and manager Alicia Etheredge is pregnant with their second child, Us Weekly reported Thursday. The magazine did not mention the baby's sex or anticipated due date. Brown and Etheredge have been married for two years. They are already the parents of a 5-year-old son named Cassius. The R&B singer has four other children from previous relationships. Bobbi Kristina Brown, his 21-year-old daughter with his late ex-wife Whitney Houston, is currently on life support in an Atlanta hospital. She was found face-down and unresponsive in a bathtub last Saturday morning. The circumstances of her medical emergency remain under investigation. Houston accidentally drowned in a hotel bathtub nearly three years ago. She was 48.
