We're kinda tired of solving this mystery, so we'll leave it to you. Is Kim Kardashian that fickle that she'd change her hair color twice in the same month, or is wearing a wig?

This pic was taken Friday in Calabasas. It paints a dark picture of Kim K ... this, just weeks after she became blonde during Paris Fashion Week.

Check out this pic Kim posted with her photographer, Ellen von Unwerth. BTW, Ellen specializes in "erotic femininity."

Now that we think about it, screw the hair. What's Kim up to now?

"Love and Hip Hop" star Masika Tucker is up in lights on the Sunset Strip, and lots of people who see her now think she's a whore ... and that has has triggered a bitter lawsuit against her co-stars.

The whole brouhaha is over a couple of strip clubs. A guy named Sam Sharif owns Ace of Diamonds in Vegas and Metropolitan Nightclub in WeHo, which has an Ace of Diamonds night every Monday.

Sharif hired Masika to promote the WeHo AOD, and part of the promotion was a big, splashy billboard on the Strip. It didn't sit well with Masika's enemies, "Love and Hip Hop" stars Nikki and Marcelle Mudarris.

Nikki and Marcelle actually rent their WeHo building to AOD, so they were really pissed off when they saw Masika's billboard. When Sharif refused to take the billboard down, Nikki and Marcelle put another billboard up nearby, with Maskika's mugshot from 10 years ago with the word "T.H.O.T."

Sharif says that billboard has torpedoed his business because he was catering to high-end clients and now people thinks it's a sleazy club advertised by a whore. He also says people think he's a fraud and really doesn't own the club.

Money cures all, and Sharif is suing for a million bucks.

"Shark Tank" star Robert Herjavec has an interesting way of saying goodbye to his "friends" ... by planting a big, juicy wet one on their smackers.

Robert and his "Dancing with the Stars" partner Kym Johnson were leaving Greenblatt's Deli in Hollywood Friday night, where they were full-on kissing.

A coy Robert explains, they're not dating ... they're just friends who dance.

They've actually been very open about their relationship ... people on DWTS all know the deal.

Ray J is pitching a new cooking show starring a guy who knows how to handle a knife ... sometimes against his own customers.

The "Love & Hip Hop: Hollywood" star believes Amy's Baking Company's fiery owners Samy and Amy Bouzaglo can carry their own show, so he and reality producer David Weintraub are pitching the couple once featured on "Kitchen Nightmares" to production companies around town. Also in the meeting was RD Whittington of Scottsdale Sports Car Group to discuss TV show plans.

You may recall the video of Samy going after a drunk and belligerent customer with a knife back in September.

We're told Ray J recently popped in to Amy's for lunch, liked what he saw and sealed the deal.

The show will be ser-rated R.

"Love & Hip Hop: Atlanta" star Joseline Hernandez must not watch her own show -- which is the only explanation for her denying under oath she ever hit Althea Eaton.

Eaton is suing Hernandez over the insane reunion show brawl. During her deposition, Eaton's attorney asked Hernandez if she has any recollection of ever hitting Eaton. You gotta watch the video of the fight and then listen to her answers.

So who are you gonna believe ... her or your lyin' eyes?

By the size of her monstrous camel sacks ... you wouldn't know reality star Lacey Wildd is starving -- but she's 6 weeks into a dangerous diet ... all to become an extreme real life Barbie.

The 46-year-old mother of six (eight if you count the twins) has undergone 36 plastic surgeries -- but is scrambling to shed as many pounds as possible before her 37th, which will be -- you guessed it ... another boob job.

TLC's "My Strange Addiction" and "Botched" star is going from LLL to QQQ, and says she's dropped 22 lbs by eating nothing more than an apple a day.

She says doctors have warned her to stop, but she's determined to become a walking cartoon character.

Note to Lacey: Mission accomplished.

"Shark Tank" star Robert Herjavec has a new asset in his portfolio -- his "Dancing With the Stars" partner Kym Johnson ... and she gets an awesome gift from him if they win.

Herjavec and Johnson met mid-February right before the "DWTS" cast was announced ... and we're told they started dating immediately.

They spent Saturday night at a party in the Hollywood Hills and Monday at Hyde lounge with the "DWTS" cast. Our spies tell us they're very open about the relationship ... lots of making out.

Herjavec has also promised Johnson if they win "DWTS" she'll get one of his Ferraris.

We broke the story earlier this month Herjavec and his wife of nearly 25 years had separated and were heading for divorce.

Things move quickly with Bob.

"Real World" star Ryan Knight's death was caused by a deadly mix of multiple drugs and alcohol according to the final autopsy report.

The Kenosha County medical examiner concluded Knight had various drugs in his system, including methadone (a heroin substitute), tramadol (a painkiller), cocaine and Xanax -- mixed with a high level of alcohol.

The medical examiner ruled the death an accidental overdose.

TMZ broke the story ... Knight was found dead and covered in his own vomit in November, after partying hard in Kenosha, WI.

Knight was 29 years old.

It looks like an engagement ring ... she's flaunting it like an engagement ring ... but the rock on Erin Andrews' finger is NOT an engagement ring.

Andrews has been dating L.A. Kings superstar Jarret Stoll for a while ... after she posted a pic with that huge diamond before last night's "Dancing with the Stars" premiere, there was buzz that he finally popped the question.

Turns out ... the ring wasn't from Stoll -- it was from wardrobe ... specifically so Erin would look "blinged out" for the big show.

But the ring was no cheap prop -- according to E!, it was a special asscher-cut diamond ring that weighed in at 2.01 carats with 22 baguette diamonds and 88 other microset diamonds.

DJ Pauly D just dropped nearly half a million bucks on a ride to Vegas ... he snagged Dan Bilzerian's sick Lambo and hit the high desert.

Things are going EXTREMELY well for Pauly … our car sources say he helped Instagram's Most Interesting Man lighten his crazy load of exotic cars by nabbing the Lambo DB posted on Ebay, for only $450k, then blazed his way to Sin City.

Bilzerian was asking $500k for the 2013 Aventador Roadster ... and nobody bit, but Pauly took it for a spin Monday, Dan dropped his price, and they sealed the deal.

Pauly -- who's doing a residency at the Vegas Hard Rock -- tells TMZ ... the car's a monster and he's always wanted it ... he even bought his daughter one -- think PowerWheels.

Only thing it needs is a fresh coat of bronzer.

NeNe Leakes ain't the next Joan Rivers yet ... but she's acting like she's got that "Fashion Police" cash by snagging a $2.1 mil Georgia estate.

According to our real estate sources ... NeNe plunked down $750k on the 9,511 sq. ft., 6 bed, 7 bath villa nestled in the swank gated Sugarloaf Country Club.

Apparently, between "The Real Housewives of Atlanta," her appearances and her HSN clothing line, she's doing more than fine ... and now, when she's not brushing up on fashion, she can hit the links and work on her swing.

But we know who she'd really like to practice her swing on ... looking at you Cynthia.

Scott Disick is fed up with traditional rehab treatments, so he's taking an all natural option -- as in sucking down hallucinogenic plants in the jungle ... under the supervision of a shaman, of course.

As we reported ... Scott checked into the Rythmia Life Advancement Center in Costa Rica, where we're told they use the African psychedelic shrub Iboga to send patients on a vision quest.

Hang with us ... it's about get even trippier. These "Iboga flights" are supposed to force users to examine their inner selves so they can learn what triggers their addictions. Sources connected to Scott tell us a shaman observes the entire trip, and the center says it's so effective ... it boasts a money back guarantee.

We're told Disick briefly visited the facility last month to research the place and was convinced Iboga could help him fight his alcohol demons.

Treatment can take several weeks, or as brief as one week -- but that would be one helluva trip ... we're guessing.

Bruce Jenner is continuing his ride to transform, because we've learned a few weeks ago he got a nose job to smooth things out.

Sources close to Bruce say the goal was to "soften" his features and make his nose look more feminine. Must say ... it worked.

It's the latest in a series of physical changes, that included a laryngeal shave to smooth out his Adam's Apple.

As we reported Bruce has also been undergoing hormone treatments and has been undergoing therapy for the transformation ... therapy that has been going on for years.

Michael Sam blew the judges away last night ... at least his ass did ... because the wannabe NFL star's booty was the talk of the ballroom on last night's "Dancing with the Stars."

The dancing was fine. His footwork was sloppy ... but after Sam cut a rug to "Uptown Funk," judges Bruno and Len couldn't stop talking about the junk in Sam's trunk.

Bruno -- "That butt was a work of art. Michelangelo's 'David' has nothing on you."

Len -- "You could win 'Rear of the Year' and I could win 'Ass of the Past.'

Scott Disick has decided to go to rehab, after an insane, tequila-fueled weekend.

Disick checked into Rythmia Life Advancement Center in Costa Rica. He says, "I realize my issues are bigger than me and I'm ready to truly remedy this struggle I continue to battle."

Scott was in Atlantic City over the weekend where he did multiple shots of tequila right out in the open. He then went on a rant onstage and ended the night at 8 AM, where he was stumbling in the hotel lobby without shoes. At 5 PM people went to his room to do a welfare check when he was MIA.

Scott has had multiple problems with alcohol and has vowed to maintain his sobriety, especially after his girlfriend Kourtney gave him an ultimatum.

As for his treatment, he says he is doing Iboga treatment, which involves roots from a small African tree that supposedly helps people battle addiction.

As for the facility, Rythmia is located on a private estate offering a "luxurious world-class experience" including a five-star restaurant, full-service spa with mud bath, and fitness center.

Scott Disick was found stumbling around drunk the morning after a tequila-soaked club appearance in Atlantic City ... TMZ has learned.

Talk about a long night ... according to hotel sources who were dealing directly with Disick ... Scott was incoherently staggering around the Harrah's lobby without his shoes at 8 AM Sunday, and had to be escorted back to his room by a hotel supervisor.

When Disick arrived at the club Saturday night he immediately grabbed the mic from the DJ, and screamed London can suck his "d*** and balls." Our hotel sources say he then proceeded to get trashed on tequila and beer, and hosed down girls with champagne.

Sunday morning hotel security was sent to check on him after he missed his check-out time by 6 hours and multiple failed attempts to reach him.

The good news? He missed his flight, but still somehow managed to make an appearance in Chicago Sunday night.

We reached out to Scott and his reps for comment ... but no word back.
