Bobbi Kristina Brown won’t be attending her dad Bobby’s nuptial festivities this weekend — sparking further rumors that they’re growing apart following the death of her mother, Whitney Houston. Bobby Brown and Alicia Etheridge, who have been engaged since May 2010 and have one child together, were expected to tie the knot in front of friends and family in Hawaii this weekend. But Bobbi Kristina wants nothing to do with the wedding and instead opted to stay in New York, where she’s shooting scenes for her upcoming reality show for Lifetime at Midtown restaurant The Hill. Whitney’s mother, Cissy Houston, is also slated to appear on the series.
