Following the Feb. 11 death of mom Whitney Houston, a grieving Bobbi Kristina Brown leaned heavily on Nick Gordon, who was unofficially adopted by the pop queen when he was 12. "We were best friends … a long time ago, and now, I'm in love with him," Bobbi explained during the October premiere of "The Houstons: On Our Own." "People were saying it's incest … none of that. You guys can take my word for it." As the pair teased a possible engagement, Bobbi declared, "They wanna see us fail. I've got one thing to say: You won't!" Or will they? In November, Gordon tweeted that he and Bobbi Kristina weren't "engaged or dating. Just close like we have always been."
