It costs $65-per-hour to spy on your ex-husband ... this according to a private eye who claims he spent months snooping around for "Gossip Girl" star Kelly Rutherford ... only to get stiffed when the bill came.

The divorce between Rutherford and her ex-husband Daniel Giersch was EPICALLY NASTY -- with restraining orders and allegations of child endangerment.

According to a lawsuit, obtained by TMZ, Rutherford hired a private eye to spy on her ex in April 2010 ... "in relation to certain issues regarding child custody and other matters."

The private eye, Edward Banach, claims he worked on the case for a couple of months ... racking up a total bill of $86,249.85 ... but only got paid $28,214.35.

Now, Banach -- who was sub-contracted through a now-defunct security company -- is suing the business AND Rutherford to get the remaining $58k. 

FYI -- At the height of the legal war between Kelly and Giersch, the actress admitted she hired a P.I. ... to prove her ex didn't properly secure the pool and play areas at his home -- which she said endangered the couple's 2-year-old son Hermes.

Rutherford explained, "I was concerned about my son's safety."

We called Kelly for comment on this story -- so far, no response.

Blake Lively just got 3 more years protection from an obsessed fan, who allegedly claimed he had a "metaphysical" connection with the actress -- because a judge extended Blake's restraining order today.

TMZ broke the story ... Blake obtained a temporary restraining order against Sergei Mifle last month -- claiming the guy made repeated contact with Blake's mom, begging to help Blake because she was troubled.

According to Blake, Sergei was spotted lurking around the set of "Gossip Girl" -- insisting he was there to help Blake "heal."

The judge extended the protective order today in L.A. -- requiring Sergei to stay at least 100 yards away from Blake and her mom for the next three years.

Blake Lively just got a restraining order against a fan she claims was lurking around the set of "Gossip Girl" -- a fan who claims to have a "metaphysical" connection with the actress and was there "to help me heal." 

The fan -- Sergei Mifle -- allegedly made repeated contact with Blake's mom, telling her he was "deeply concerned" about her daughter and claimed he needed to help her because she was troubled.

A picture of Sergei was attached as an exhibit to Blake's petition (below).


Blake says in her declaration she's fearful about her personal safety and the safety of her mother.

The judge issued the restraining order, which prohibits Mifle from coming anywhere near the actress or her mom.

Leighton Meester's mom is firing back after her daughter sued her last week -- claiming in a new countersuit, Leighton threw her to the ground back in December ... "repeatedly hitting her with a bottle."



According to the countersuit, filed in L.A. County Superior Court, at 2:00 AM on December 11, 2010, the "Gossip Girl" actress attacked her mom with the bottle and was so crazed she had to be pulled off her mom by her little brother.

Constance Meester says it's true ... Leighton sent her $7,500 every month, but that was not out of the goodness of her heart.  It was -- Constance claims --  a settlement for all the money she helped make for her daughter.

Story developing...

"Gossip Girl" star  Leighton Meester is suing her mother, claiming her mom diverted money Leighton sent to her little brother and used it for plastic surgery, Botox and hair extensions.
 


According to the suit ... obtained by TMZ ... Leighton's mom refused to work, but Leighton felt badly for her younger brother Lex, who has severe medical issues.  So Leighton sent her mom $7,500 a month so she could provide for Lex.

But the suit claims the mother, Constance Meester, used the money for cosmetic procedures and other personal expenses.

According to the suit, Constance even tried to convince Leighton ... they had an oral contract requiring Leighton to pay her $10,000 a month for life.  Leighton says it's a total lie. 

Leighton claims her mom threatened to file a $3 million lawsuit against her unless Leighton started coughing up the dough.

Leighton wants the judge to declare there's no contract between her and her mom.

The hacker who claims to have naked pictures of Blake Lively has just upped the ante, scoffing at claims the pics are photoshopped ... and he's posted more pictures to prove his case.



The hacker just posted 17 additional pics. Many of the pics show a nude woman whom the hacker insists is Blake.

Blake's people are adamant ... telling TMZ the person in the pics is not Blake.  The denial apparently incited the hacker, who posted the new pics, with this warning:  "Oh, yes, Blake's rep. These are totally fake.  We really, really believe you.  Want moar?  BTW, thanks for all the faps." (FYI: "faps" is a reference to pleasuring oneself)

Two of the pics show a woman clothed, holding an iPhone, and it sure looks like Blake.



Several of the nude pics show a woman's body with tattoos (no face).  Several TMZ users contacted us with an interesting point ... Blake's character in "The Town" had star tattoos on her upper-chest area.
 

The photos circulating around the Internet purporting to be Blake Lively are fake, phony, Photoshopped, fabricated, fictional, false ... so says Blake and her people.



Sources with intimate knowledge of the actress' physical features tell TMZ ... it's simply NOT Blake's body ... and there are definitive markers proving the pics are fake.



Blake has hired a lawyer who is sending threatening letters to anyone who publishes the pics and implies it's her.

We did notice a 2008 photo of Blake holding the exact same phone as the one shown above, but the phone is pretty common.

Ex-"Gossip Girl" star Dreama Walker -- who currently plays Becca on "The Good Wife" -- just got her ass sued in L.A. ... after allegedly plowing her rental car into another vehicle ... and causing serious damage.


The alleged victim filed a lawsuit in L.A. County Superior Court recently -- claiming Walker drove STRAIGHT into her car back in March ... not only destroying her ride, but causing her considerable personal injury.

The woman behind the lawsuit is now suing Walker for medical bills, loss of earnings, and car repair costs.

Calls to Walker weren't returned.

Having apparently lost some sort of bet, "Gossip Girl" star Leighton Meester showed up to an event in NYC last night leaving little to the imagination ... by wearing an unfortunate lacy sheer butt-flashing genie pant one-piece jumper thing.



Blair Waldorf is not going to be happy about this.

Blake Lively and Penn Badgley know breaking up is hard to do ... when you work together.



For the first time since news broke of their breakup, the former couple was spotted smiling and embracing on the NYC set of "Gossip Girl" today.

XOXO ... but only on-camera.

Looking like the Corpse Bride of Chucky, "Gossip Girl" star Taylor Momsen continued with her underage-goth-girl-rocker-peek-a-boo-leather-and-lace-fashion-zombie tour in West Hollywood last night.



Believe it or not, the 17-year-old lead singer of The Pretty Reckless was not in costume for Halloween.
