Whitney Houston's daughter Bobbi Kristina and her BF were double-teaming a hand-rolled cigarette in Atlanta yesterday ... almost one year to the day Whitney died from a drug overdose.

It's unclear what's inside the rolling paper -- but c'mon.

It's interesting, considering Whitney's mother Cissy Houston has been vocal about her concerns that Bobbi Kristina could follow Whitney's path into drug abuse unless she drastically changes her life.

Bobbi's been at war with her grandmother for months ... and recently slammed Cissy for writing a tell-all book about Whitney.

Whitney passed away on Feb. 11, 2012 after going on a drug binge that included coke, pills and marijuana.

Bobbi Kristina is on a mission to make sure grandma Cissy Houston's new tell-all book crashes and burns -- by BOYCOTTING it altogether and pleading with her fans to do the same.

Cissy released a book this week called "Remembering Whitney" -- which is all about Whitney Houston's life -- and made the rounds on a slew the talk shows promoting the hell out of it.

But Bobbi wasn't too happy, tweeting to her 119,000 plus followers, "Anything concerning my grandmother's book, I and @nickgordon of course personally have nothing to with."

She continues, "I haven't read and won't ... I find it to be disrespectful to my mother and me being her daughter won't tolerate it."

FYI -- Cissy was on Oprah earlier this week (again promoting the book) and admitted her relationship with BK was strained ... and admitted she knew that Bobbi didn't want the book written.

Bobbi Kristina has finally gotten rid of the black Chevy Camaro she smashed up on multiple occasions -- replacing the car with something she believes is MUCH safer to drive ... TMZ has learned.

According to sources close to Whitney Houston's daughter, the girl purchased a 2013 Lexus IS 250 right before Christmas -- and is telling friends she feels much more comfortable driving the new car than she did the Camaro.

Bobbi feels the visibility in the new whip is a LOT better -- which might help lead to fewer accidents.

As we reported, Bobbi crashed her old Camaro multiple times -- first into her boyfriend's parked car, then into several trees on a Georgia embankment. She was also involved in a third accident in the Camaro, riding in the passenger seat.

Unfortunately, chances are it's the driver ... not the car.

Bobbi Kristina's boyfriend Nick Gordon was listening to the Whitney Houston classic "I Will Always Love You" at FULL BLAST when police pulled him over for reckless driving -- and TMZ has obtained the dash cam footage of his arrest.

In the video, Gordon tells the police officer he keeps a 9mm gun in his glove box. The cop checks it out after putting Gordon in his cruiser, and based on the video, it appears the gun is legit.

We broke the story ... Nick was popped in Alpharetta, Georgia last week just after cops say he was going 82 mph in a 35 mph zone near a pedestrian-jammed shopping area.

You can see in the video, Gordon was driving a Chevy Camaro -- the same kind of car BK was driving when she crashed into an embankment hours before Nick was arrested. 

Nick was cited for reckless driving and speeding. He's due back in court in February.

Nick Gordon -- Bobbi Kristina's boyfriend -- was ALL SMILES after cops arrested him for reckless driving last night ... and TMZ has the mug shot that proves it.

We broke the story ... Nick was popped in Alpharetta, Georgia just after 6:30 pm after cops say he was going 82 mph in a 35 mph zone near a shopping area with high pedestrian foot traffic.

According to the police report, obtained by TMZ, Gordon was driving a Chevy Camaro -- the same kind of car BK was driving when she crashed into an embankment hours before Nick was arrested.

Nick was cited for reckless driving and speeding. He's due back in court in February.

Bobbi Kristina's boyfriend Nick Gordon was arrested for driving like a maniac last night ... hours after Whitney Houston's daughter totaled a Chevy Camaro in a frightening wreck of her own.

Law enforcement sources tell TMZ ... Nick was taken into custody in Alpharetta, Georgia last night ... after cops say he was going 82 in a 35 on Northpoint Parkway ... a retail area with high pedestrian foot traffic.

One law enforcement source tells us, "We are fortunate because that's such a busy corridor with high end retail shopping retaurants and pedestrains at crosswalks."

The source adds, "At that speed, it's absolutely reckless."

We broke the story ... BK wrecked a Camaro in Alpharetta yesterday after losing control and careening down an embankment ... striking several trees along the way. Miraculously, she emerged from the accident unscathed ... but cops issued her a citation for failing to stay in her lane.

Attempts to reach Nick for comment were unsuccessful.

Whitney Houston's daughter Bobbi Kristina has miraculously emerged unscathed after wrecking her Chevy Camaro in a frightening car crash moments ago ... TMZ has learned.

The accident just went down in Alpharetta, Georgia -- law enforcement tells us a passer-by noticed Bobbi's car all smashed up in an embankment and called 911.

When emergency personnel arrived at the scene, Bobbi Kristina was standing next to her vehicle and appeared to be uninjured.

Cops conducted an official accident investigation -- and believe Bobbi Kristina simply lost control of her car while making a left turn out of her apartment complex ... and drove over a curb and down an embankment, striking several small trees along the way.

Eventually, the car came to a stop on a local park trail.

After the investigation, cops issued BK a traffic citation for "failure to maintain lane."

Cops say ... it doesn't appear drugs or alcohol were a factor in the crash.

We reached out to Bobbi Kristina's camp -- so far, no word back.

Bobbi Kristina treated her boyfriend to a late-night bangin' session this week ... when she plowed her Camaro into his Camaro ... and TMZ has a photo of the wreckage.

Sources close to the couple tell TMZ ... it all went down inside the parking garage at the couple's apartment complex in Georgia on Monday night.

We're told Bobbi had followed Nick Gordon's car back to their place from another location ... and moments after he parked his car, she tried to back in to the next spot over ... and screwed up ... smashing the front of Nick's brand new car in the process.

Sources connected to the couple insist the crash was NOT alcohol related ... it was just a really expensive mistake.

Bobbi Kristina's grandmother Cissy Houston has BACKED OFF her attempt to keep Whitney Houston's money from Bobbi Kristina for years -- we found out Cissy has settled her beef with BK.

TMZ broke the story ... Cissy and Pat Houston (co-executors of Whitney's estate) ... had filed legal papers hoping to drastically change the way Whitney's fortune would be paid out to 19-year-old Bobbi .. because they felt it was "too much, too soon."

As it stood, BK was to receive her money -- an estimated $20 million -- in 3 separate chunks ... 10% when she turns 21 ($2 mil), just under 20% at age 25 ($4 mil) and the remainder when she turns 30 ($16 mil).

Now, we've learned ... the case has been dismissed after Bobbi and Cissy reached an agreement ... and sources tell us Whitney's original plan for the payout was virtually unchanged.

Still, we're told both Bobbi and Cissy are satisfied with the plan ... and are happy to put the case behind them.

Whitney Houston's daughter Bobbi Kristina has a serious drinking problem ... so say family members and close friends who tell TMZ it's gotten even worse since she finished taping her reality show ... and they fear she could die unless she does something about it.

We broke the story ... many people close to B.K. feel she has allowed some of Whitney's enablers to get heavily involved in her life ... and if Bobbi doesn't cut them out soon, she's doomed to the same fate as her mom.

Those people -- sources say -- include various individuals who knew about Whitney's problems, but didn't take action when the singer's life was spiraling out of control.

Bobbi's problems were highlighted during the premiere episode of her Lifetime series, "The Houstons: On Our Own" ... which featured 19-year-old Bobbi slamming wine and slurring. The episode was taped a few months ago ... and our sources say the boozing has only gotten worse since the show wrapped.

During a tease for an upcoming episode, an emotional Pat Houston suggests taking Bobbi to California ... where Whitney received treatment from a drug counselor before she died.

Sources close to B.K. tell us ... they DON'T WANT Bobbi to see the same counselor, because they feel he did not help Whitney ... and will fail again with Bobbi.

Bobbi Kristina's boyfriend, Nick Gordon, got a brand, new ride following his NASTY car accident last month  -- and wouldn't you know ... he took home THE EXACT SAME CAR he had before.

TMZ broke the story, Nick and B.K. got into a scary accident in GA last month and his precious Chevy Camaro was badly wrecked -- with the bumper torn off and a missing front tire (below).

The details surrounding the crash remain unclear -- but we're told the accident is currently under investigation.

In the meantime, sources close to Nick tell TMZ ... he wasted no time replacing his messed up ride -- and even though he had his heart set on a Maserati, he ultimately went with a new Camaro, just like his old one.


But in dark grey, NOT black -- biiiiiig difference.
