Bobbi Kristina Brown and Nick Gordon ink “WH” tattoo on their wrists to mark Whitney Houston’s 49th

Bobbi Kristina Brown has paid tribute to her mother Whitney Houston by inking a tattoo on her wrist in her honor.

Marking what would have been Whitney Houston’s 49th birthday today, the 19-year-old old and her boyfriend Nick Gordon had matching tattoos with Houston’s initials framed by four doves etched on their wrists.

In a series of tweets, Bobbi Kristina Brown wrote late last night: “Once it hits 12 am mommy it’s your birthday & I am going2celebrate it2thee fullest!”

She continued: “Bc YOU deserve it damn it, YOU deaerveNothingburtheBEST! [sic]”

Bobbi Kristina Brown, who is said to be dating her “adoptive brother” Nick Gordon, explained they were heading to a tattoo parlor for a session that would be filmed for her reality show, The Houston Family Chronicles.

The Lifetime series, expected to premiere in 2013, will follow the Houston family “as they take on their greatest challenge, supporting and guiding Bobbi Kristina Brown as she faces the world alone, without the one person she relied on the most, her mother”, according to the network.

Taking to Twitter, Bobbi Kristina Brown chronicled her tribute to Whitney Houston last night: “On the way with MYbooboo @nickdgordon :)heading2 #Inksomnia for our TATTSSS !this is for you mommy (: we love you, happybirthday OurladyXx

“You all will get2see! No worries :)we’ll show you & so will our #Realityshow ! #TheHoustonChronicals !make sure you look out for it nxtyr!”

Then, debuting the artwork, Bobbi Kristina Brown wrote: “Tat tat tatted YURP.. 😉 now your truly ALWAYS with us mommy (: we love you @nickdgordon always&forever[<3].”

Whitney Houston’s only child, her daughter with singer Bobby Brown, is said to have grown closer to Nick Gordon in the wake of her mother’s February 11 death, when she was found unresponsive in the bathtub of room 434 at the Beverly Hilton.

Authorities called her death an accidental drowning, complicated by heart disease and cocaine use.

While the pair are not actually being blood relatives, Bobbi Kristina Brown and Nick Gordon grew up together after Whitney Houston took him in at the age of 12 when his father went to prison and his mother was unable to take care of him.

Nick Gordon was never formally adopted by the singer, and with Bobbi Kristina Brown’s mother passing away in February couple have reportedly been sharing her $1.2 million Atlanta home together.

The 22-year-old fuelled rumors about their relationship status in a tweet written last March, exclaiming: “Yea we got a little closer and what!!!”

Bobbi Kristina Brown subsequently listed Nick Gordon as her “partner” in a short bio on the micro-blogging website.

The pair batted away rumors of an engagement shortly after, while Bobbi Kristina Brown’s grandmother, Cissy Houston, branded their relationship “incestuous” in an interview with TMZ.

Despite family feuds over the matter, the Houstons are expected to unite later this month to honor Whitney Houston’s memory with the posthumous release of her final feature film, Sparkle.

The Salim Akil drama is scheduled to premiere on August 17.
