Since Bobbi Kristina and her kinda-sorta brother Nicholas Gordon were spotted at aTarget in Georgia earlier this month, fans have speculated about the nature of their relationship. On Tuesday (March 13), the only daughter of late singer Whitney Houston shed some light on the matter, utilizing Twitter -- tweeting for the first time since Dec. 26, 2011 -- to hint that, yes, she and Nicholas are romantically involved.

Her first in a string of re-tweets was a message from Gordon, a 22-year-old described by HollywoodLife.com as Bobbi Kristina's "unofficial adopted brother."

"I've proved my loyalty to her and the Houston family," Gordon wrote and Bobbi re-tweeted. "I don't owe any of you anything. Ha I don't even know y'all haters."

What follows on Bobbi's Twitter timeline is a series of positive messages from fans.

"@ndgordon & @REALbkBrown do what ya'll do!" wrote Mizz Banks. "Don't let anyone stop ya'll! U were raised well. People hate on a evrydy basis so jus keep movin."

Houston is said to have raised Gordon as a son, though as he pointed out in a Twitter post of his own, he's not BK's blood relative. The implication: A love affair wouldn't be as creepy as it may seem, and in the photo he posted last week, the two look like a fairly normal young couple.

"For the stupid ppl out there she gave birth to 1 child," he tweeted, referring to Whitney. "And she trusted me with EVERYTHING!!!!!!!!!!!!!"
