Bobbi Kristina Brown kisses and professes love for 'brother-turned-partner'

New York, August 13 (ANI): Late Whitney Houston's daughter Bobbi Kristina Brown stunned her fans when she posted pictures on Twitter that showed her sharing a passionate kiss with her adopted brother Nick Gordon, while flaunting a huge sparkler.

The pair, who got matching dove tattoos in honour of their late mother Houston on last Wednesday, on what would have been the singer's 49th birthday, flaunted their love for the cameras on Friday.

In the image, Brown and Gordon can be seen kissing, with the singer's left hand cradling her brother-turned-boyfriend's chin.

"1 of the main reasons why i even smile today," the New York Daily News quoted her as tweeting.

"iloveyoubooboo, forever and always. 'it's just US now'," she wrote.

This isn't the first time that Brown, 19, has outwardly expressed her affections for Gordon, 22.

The previous day, she tweeted about how her "boo" Gordon was asleep next to her, and the couple sparked engagement rumours earlier this year after the singer turned actress stepped out with a ring on her finger.

"She is just wearing her mom's ring," a source had told People magazine at the time.

Gordon and Brown are not biologically related.

The late singer reportedly informally adopted Gordon at a young age after his parents were unable to take care of him, and he has been living with the Houston household ever since.

The pair's love will apparently unfold in front of cameras on Brown's upcoming reality series, 'The Houston Family Chronicles,' which is scheduled to premier next month. (ANI)
