Bobbi Kristina Brown was reportedly alone for 10 minutes

Los Angeles - Bobbi Kristina Brown was alone for "10 or 15 minutes" before her lifeless body was found.

The 21-year-old aspiring actress is currently "fighting for her life" in hospital after she was discovered facedown in the bathtub at her Atlanta home on Saturday and it has now emerged her 'husband' Nick Gordon and friend Max Lomas had begun searching for her after a cable technician visited the house and couldn't find her.

Max's attorney, Ashleigh Merchant, told E! News: "Nick was actually the one who answered the door for the cable man, and he was showing the cable man around.

"Max says that he knocked on her door and he didn't get an answer, so he went in and checked on her to see how she was doing.

"He's actually the one that found her, and he called for Nick, screamed for Nick, and then he immediately called 911.

"It seems like it might've been 10 or 15 minutes that she must have been alone... but we don't know at what point she actually ended up in the tub during that time."



Meanwhile, Bobbi Kristina's father Bobby Brown had a low-key birthday celebration on Thursday night.

Two Can Play That Game</em> singer, who has been keeping vigil at his daughter's hospital bedside, was joined by around 20 family members, including pregnant wife Alicia Etheridge and their five-year-old son Cassius, for dinner to mark him turning 46.

Bobby was met by a police officer at the door of an eatery close to the Emory University Hospital and escorted him into a private dining area, which was shielded from other diners by a drawn curtain.

The singer was said to seem "downcast and tired" but brightened at the sight of his family.

Despite a subdued atmosphere, the guests sang <em>Happy Birthday</em> to the father-of-five - who had Bobbi Kristina with late ex-wife Whitney Houston - and two birthday cakes were served later in the evening.
