"16 and Pregnant" star Whitney Purvis tells TMZ, she's had her fill of her baby daddy's slacker do-nothing lifestyle ...so she dumped the guy, and took the kid to her parents' house.

18-year-old Whitney -- who was featured on the MTV show in 2009 -- tells us, she was living with her boyfriend and their son in an apartment in Georgia up until a couple of weeks ago -- but she decided to call it quits.

According to Whitney, she ended things because her man -- Weston Gosa -- "was gone all the time.  He wouldn’t come home until 3AM in the morning ... I was home with the baby and he was nowhere to be found.”

But Whitney doesn't believe Weston was cheating -- telling us, "You know when someone is cheating on you.  He was just out with his friends all the time getting messed up ... I don’t want that around my kid.”

Whitney claims the couple was fighting constantly and she just couldn't take it anymore, so she moved back in with her parents -- and took their son with her.

Attempts to reach Weston were unsuccessful.

The NBA offseason from hell just got worse for Los Angeles Lakers player Matt Barnes ... who just announced that he's officially broken up with his "Basketball Wives" baby mama Gloria Govan.

Barnes -- who has 2 children with Govan -- just released a statement saying, "We have reached the difficult decision of ending our relationship and will be going our separate ways at this time."

He adds, "We will work together to raise our sons and wish each other only the best."

Barnes and Govan have had some issues in the past -- including the time Matt was arrested on suspicion of domestic violence back in 2010 ... but prosecutors didn't press charges due to a lack of evidence.

Deal of the century -- some mystery buyer just purchased the massive engagement ring Hugh Hefner gave to Crystal Harris ... for a fraction of the original $90,000 price tag.

Sources tell TMZ, the unidentified bidder won Crystal's auction this morning -- bidding $38,000 for the 3.39 carat circular-cut diamond. With taxes and fees, the final bill was $47,500.

Shockingly, the ring actually exceeded auctioneer expectations -- because it was only supposed to sell for $20 -$30k.

Hugh reportedly shelled out the full $90k for the ring when he proposed to Crystal less than a year ago -- but Crystal called the wedding off.

The relationship they said would never last ... didn't last.

"Dancing with the Stars" pro Mark Ballas and "American Idol" hottie Pia Toscano have officially broken up ... according to People.com.  The split is said to be "mutual."

Mark is currently training with his "Dancing" partner Kristin Cavallari ... and Pia ... is ... um ... well, she's still hot.

Kristin Cavallari threw on a small black dress and hit up a hotspot last night she KNEW she'd get photographed at ... STK in Hollywood. 

Eat your heart out, Mr. Cutler.

 

Kat Von D lives her life with "no regrets" -- which is exactly why she's NOT removing a big ass tattoo of Jesse James' face from her ribcage ... DESPITE the end of their relationship.

Kat tells TMZ, "I love my tattoo" -- adding, "It's more than just a portrait, it has a lot of meaning."
FYI -- the tat is a school picture of Jesse ... from when he was in the FIFTH GRADE.
Kat -- whose show "L.A. Ink" premieres tonight on TLC -- also has a tattoo of another ex-BF somewhere on her body ... and she tells us, that's not going anywhere either.
Dedication.

Kat Von D says she had a DAMN good reason for walking off "Good Day L.A." this morning -- telling TMZ, she made one reasonable request ... and producers repeatedly BLEW HER OFF.

Kat tells us, she agreed to answer a question about her breakup from Jesse James on one condition -- that the anchor didn't mention the split in his introduction.

But according to Kat, that request was IGNORED -- and as we previously reported, anchor Jeff Michael read out an introduction that highlighted Kat and Jesse's breakup.

Kat says she saw what was on the teleprompter long before Jeff read it -- and even pulled a producer aside to have someone change the script ... but nothing happened.
According to Kat, she "very politely" informed them ... if it wasn't changed, she wouldn't be able to go on. But no one changed squat, so Kat beat it.
Later, during the show, the executive producer went on the air -- explaining Kat's only prior request was not to bring up Sandra Bullock or Michelle McGee ... a request "Good Day" honored.
Nevertheless, Kat adds, "I have no interest in going back on, but I wish them all the best."

Kat Von D walked off the set of "Good Day L.A." this morning ... minutes before she was set to give an interview -- and we're told, it was all because the anchor mentioned her breakup with Jesse James.

Sources on set tell TMZ, Kat was all set to give the interview -- but flipped out when she heard how she was introduced on the show ... and walked out of the building before the interview even started.

During the introduction, "Good Day" aired a clip from Kat's show "L.A. Ink" -- showing Kat getting a tattoo of Jesse James on her side -- and anchor Jeff Michael mentioned she got the tattoo before she and Jesse called it quits.

According to sources, Kat was pissed Michael even brought up her relationship with Jesse ... and stormed out of the building.
 We're told Kat approved the Jesse James tattoo clip from her show -- and even got a heads up from "Good Day" producers that she would be asked about the breakup during the interview.
 It's unclear what exactly went wrong -- but Kat just tweeted, "Dear GoodDayLA, thanks for the waste of a perfectly good morning. Lack of compassion n respect for each other never fails to disappoint me."
 UPDATE: "Good Day" host Jillian Reynolds just went OFF on Kat for ditching the interview ... you gotta watch this clip!

In one of the worst cases of horrible timing EVER, Kristin Cavallari posed in wedding dresses for a photo shoot last Thursday -- 4 days before it was announced her engagement to Jay Cutler was OVER.


At first glance, the pics seem to back up reports the Chicago Bears QB was the one who did the dumping ... because why the hell would K-Cav put herself through the misery of a wedding shoot if she was contemplating breaking off the engagement??? 

On the other hand, why the hell would Jay Cutler let her go forward with a photo shoot in wedding gowns if he was gonna dump her ass a few days later ... unless he's just a mean person.

With her engagement to Jay Cutler called off, a ringless Kristin Cavallari walked her dog by herself in West Hollywood on Monday.


She may not have her man, but she's still got man's best friend.

Chicago Bears quarterback Jay Cutler will be about 110 pounds lighter when he enters training camp this year ... because he just dropped his fiancee, ex-MTV star Kristin Cavallari.



10 months after they began dating ... and just 3 months after they got engaged ... People.com is reporting the couple has split ... and suggest it was Jay who did the dumping.

Pretty shocking news considering they just hit Miami together earlier this month.

Don't be shocked if Kristin begins rooting for the Packers.
