Singer Bobby Brown , his wife Alicia Etheridge and their son Cassius Brown are seen at the Soul Train Awards 2012 at PH Live at Planet Hollywood Resort & Casino on November 8, 2012 in Las Vegas, Nevada. The "My Prerogative" singer has been given something to smile about as he maintains a bedside vigil over Bobbi Kristina Brown, his only daughter from his marriage to tragic Whitney Houston - his wife Alicia Etheridge has given birth to the couple's second child.
