Los Angeles, May 26 (IANS): Late pop star Michael Jackson's son Blanket Jackson struggled over the years with his name as his peers in school used to bully him regarding the name.

Jackson is survived by three children-- Michael Joseph Jackson Jr, Paris Michael Jackson and Prince Michael Jackson II who is nicknamed Blanket.

Prince Michael Jackson II, who is 15-years-old now, has been bullied for his name for years together. He has changed his name to Bigi, and now Bigi has turned out to be a very confident, positive teenager and has become socially active by interacting freely with his family and friends, reports people.com.

It's not exactly clear who is directly in charge of the teenager, whose mother was an unidentified surrogate - due to ongoing family disputes, but the 15-year-old lives at grandmother Katherine Jackson's Calabasas, California, mansion under the custody of Katherine, 87, and co-guardian T.J. Jackson, 38, Michael's nephew.

"The children live like Michael is constantly looking down upon them," said a family friend.
