Bobbi Kristina Brown has been spotted wearing a sparkly bauble on her ring finger, but she\'s not planning on getting married anytime soon. A representative for Brown\'s mother, the late Whitney Houston, says the 19-year-old is \"simply wearing her mother\'s ring\" and that she\'s not engaged. Rumours about a possible engagement flew after Brown was spotted snuggling with friend Nick Gordon while wearing the ring. Brown has been the subject of intense scrutiny since her superstar mother died last month. Brown\'s father is Bobby Brown. Houston left her entire estate to her daughter, her only child.
