Citing sources close to the case, a reporter with Atlanta's WSB-TV says police are now investigating injuries to Bobbi Kristina Brown's face and boyfriend Nick Gordon's hands.

Authorities in Georgia have reportedly launched a criminal investigation into the case of Bobby Kristina Brown, who was found unresponsive in a bathtub last weekend and has been in a medically-induced coma since.

Around the time of Whitney Houston's death, it became apparent that her daughter Bobbi Kristina Brown was dating Nick Gordon, who had been unofficially adopted by Houston after high school. This week, the two announced their marriage on Twitter with a photo of rings on their hands.

Young love: so magical when it happens in movies, so annoying when it happens in real life because this Chili's is for everyone and families are trying to eat dinner here. Sophomores dating juniors. Cheerleaders dating lacrosse captains. Brothers dating sisters. Everything cool except that last one.

Whitney Houston's daughter Bobbi Kristina Brown has been out of the news since she reaffirmed her love for her adoptive brother Nick Gordon last month, but it appears she's about to make a comeback.

The rumors had been swirling for a while, but now there is video evidence that Whitney Houston's notoriously troubled daughter Bobbi Kristina, age 19, is doing sexy things with adopted brother Nick Gordon, age 22.
