Whitney Houston's daughter, Bobbi Kristina, 19, is dating family friend Nick Gordon, according to
Hollywoodlife.com. Gordon, 22, was taken in by Whitney when he was 12, but was never officially adopted by the late singer.
The two youngsters seemed more like siblings, with Bobbi Kristina describing Gordon as "brudder," and Nick calling her "li'l sis."
Rumors of a romance were sparked after Bobbi and Gordon were spotted kissing and holding hands last Friday outside of a Target in Georgia.
Nick's recent tweets have also fueled speculation. He wrote, "Yea we got a little closer and what!!!"
Gordon also took to the social networking site to alert Bobbi Kristina's fans to only follow her real account. "Good morning everyone. Their lots of fake people pretending to be MY Krissi. The real one is @REALbkBrown. Fakes need to get un followed (sic)"
Bobbi Kristina has not been on Twitter since December, but she and Nick tweeted each other regularly before that.
According to TMZ, Whitney unofficially adopted Nick 10 years ago after she learned that his mother was unable to care for him.
Bobbi recently opened up to Oprah, telling her, "I can hear [my mother's] spirit talking to me, 'I'm right here, I've got you.' I can always feel her with me."
