Bobbi Kristina Houston did not attend Bobby Brown's wedding "because she did not like his partner".
The 19-year-old daughter of the singer and his late ex-wife Whitney Houston, missed the June 18 nuptials to Alicia Etheridge.
A source told Us Weekly magazine: "Bobby Brown was desperate for her to go to his recent wedding, but she would not return his calls.
"Bobby got a go-between to contact Bobbi Kristina to try and persuade her, but she told them she was not going because she did not like Alicia, and that she was [busy] filming her reality show with [aunt] Pat Houston in New York."
The source added that Bobbi Kristina's aunt Pat - Whitney's sister - is doing her best to pose as a parental figure.
The insider added: "She's trying to act like a mother figure. Pat does not like Bobby Brown and was pleased that Bobbi Kristina did not go to the wedding, as she feels that her father will always try and take advantage of her."
In April, the pair united during a tense lunch in New York City.
According to an eyewitness: "[Bobbi Kristina] was on her phone and texting a crazy amount. She didn't seem too thrilled to be there, in all honesty."
