Backstreet Boys singer Brian Littrell's six-year-old son, Baylee, has been hospitalized. A Thursday blog post on Brian's Web site reads: “For those of you who do not know or have not heard, Baylee Litrell has been in the hospital for the past few days. He will be starting a treatment this afternoon and the Littrell family asks that all Backstreet Boys fans please remember him in prayer during this trying time.” Brian and his wife Leighanne wish fans Happy Holidays and say more updates on their son's health will follow.
