Bobbi Kristina Brown and her adopted brother and boyfriend Nick Gordon are engaged, according to a preview for Lifetime's reality show "The Houstons: On Our Own."

In the clip obtained by E! News, Brown is heard telling her family, "We're engaged!"

Rumors had been circulating that the 19-year-old Brown was engaged to Gordon, but the speculation was refuted by a rep for Brown.

In the clip Brown's family members don't appear to take the news very well. "The Houstons" premieres Wednesday, Oct. 24, on Lifetime.
