bobby brown (tmz screenshot)*Clearly Bobby Brown is not too thrilled about his daughter with Whitney Houston, Bobbi Kristin, getting married to Nick Gordon.

We found that out when a TMZ video guy asked him his thoughts:

TMZ Photog: “How excited are you for your daughter — she’s about to get married and stuff?”

Bobby Brown: “I’M NOT.”

Yep, there it is. B. Brown is not feeling the upcoming nuptials between his lil’ girl and Nick “He’s Not My Biological Brother” Gordon.

He also said Nick never even called him up to ask for her hand in marriage.

The Brown family isn’t exactly the tightest bunch — Bobbi Kristina doesn’t talk to her dad, so why would Nick?

Still let’s recap … the not-official brother didn’t call his quasi step-dad to ask permission to marry his kinda-sister.

Despite the bitterness, Bobby tells TMZ … “I just want her to be happy.”

As we reported, Bobbi K revealed the engagement on Facebook last week … and though her mother, the late Whitney Houston, treated Nick like a son growing up, he’s not a blood relative and was never formally adopted.
