Gossip Girl

But fear not Upper East Siders, Blake's boyfriend Penn Badgley was reportedly there too.

Decked out in Miley Cyrus shades, a Selena Gomez jacket, a Demi Lovato t-shirt, Dakota Fanning pants and a pair of Mary-Kate Olsen boots, Taylor's adult mother Collette accompanied her more matronly-attired teen spawn to the NYC set of her TV series on Wednesday.

Remember when you were embarrassed by your mom in high school?

The striptease went down at Ed's girlfriend's and fellow cast mate Jessic Szohr's friend's wedding reception in Milwaukee recently.

What would Chuck Bass do?

On Thursday, Hilary Duff became the latest in a long line of freshly blown out celebs to find an expired meter and a citation after leaving the WeHo hair studio.

TMZ has learned Kelly Rutherford was granted a temporary restraining order against her ex Daniel Giersch.

According to documents filed in L.A. County Superior Court, Kelly claims Daniel has repeatedly harassed both her and their nanny -- which she claims forced the nanny to quit.

The documents list Giersch as 39-years-old, white, and "thin."

Geirsch must stay 100 yards away from Kelly, her mother, the nanny, and Kelly's home, job and vehicle -- "except for brief & peaceful contact as required for court-ordered visitation."

In the docs, it says "Daniel has begun to follow me, my mother, my nanny and he shows up unexpectedly to threaten and scare us."

Kelly also claims Daniel "has harassed [my nanny] with questions about me virtually every time he sees her ... last week Daniel's harassment of [the nanny] led to an actual threat that he is going to file a lawsuit against her."

After that, Kelly says the nanny handed in her pink slip, causing her two kids -- Hermes and Helena -- to lose someone they "love and trust."

Little J has to pay big bucks to her record company if she takes on any acting gigs with "musical elements" -- but there's a catch...

We just got our hands on Taylor Momsen's record contract with Interscope Records -- dated March 17, 2009 -- which states if she takes a role as a musician or band member -- she has to fork over 10% of her paycheck for that gig to her musical overlords.

Now to the catch -- Momsen included a clause in the contract which allows her to sing her little heart out for free on two projects ... "Gossip Girl" and an upcoming "Runaways Project."

The only Runaways project we've heard of is the Joan Jett bio-pic staring Kristin Stewart -- and as far as we know, Taylor isn't part of the cast.

So, either we just blew a huge Hollywood secret ... or the 16-year-old got a serious taste of bigtime movieland rejection.

Between them, they have three stints in rehab. All Lindsay's.

The two were spotted in the backseat lip-lock while Chace was dropping Ashley off at LAX.

We're told the couple has been spotted together "quite often" recently, but no one suspected that they were more than just "good friends" ... until now.

XOXO

Kelly Rutherford just settled her custody dispute with ex Daniel Giersch -- at least until April 2010.

The "Gossip Girl" matriarch filed for divorce in December 2008. The couple has two children together -- one of whom was born less than two months ago.

Rutherford and Giersch had a heated battle over custody that nearly kept Rutherford from filming scenes for "Gossip Girl."

Settlement documents have been filed with the court. Under the terms, both Kelly and Daniel will temporarily relocate from California to New York while she films "Gossip Girl" -- from July 30 through April 5. She'll live in NYC and he'll live in the Hamptons. Neither party can travel outside of New York or California without the agreement of the other.

The docs say both parents will attend co-parenting counseling sessions.

The show mimics "Gossip Girl" ... with a healthy dose of drugs and sex. Two of the show's stars, recent Dwight School grads "PC" Peterson and Jessie Leavitt, went on the air yakking about booze, sex, and smoking up -- and that was just the first episode.

The Dwight School is apparently panicked that other students will appear in similar shows exhibiting similar debauchery. So they sent a letter to the student body and alums, expressing a "zero tolerance." But the letter is so confusing, it's not clear if school honchos mean a zero tolerance for drugs and sex or a zero tolerance for appearing on reality shows.

Another "Gossip Girl" star in the news. Kelly Rutherford is apparently worried that her ex might leave the country with the couple's two children, Hermes and Helena.

We got our hands on docs filed yesterday in their custody war -- both Rutherford and her estranged hubby Daniel Giersch have agreed he will ante up his visa and visa application to her lawyer within a week.

The docs don't say why this is happening, but the application is telling -- it seems Giersch may have plans to leave the country, smack in the middle of their ongoing fight over the kids. Giersch is from Germany.

UPDATE 9:40 AM ET: Apparently the deal has been closed, because celebhotline.com has pics of what looks like the video on its site.

Spotted ... "Gossip Girl" star Leighton Meester having sex with her BF... on video.

We've learned a Meester tape is being shopped around town. It was shot a few years back, and shows Leighton in mostly innocuous though nude scenes -- with several big exceptions ... one involving her very talented feet.

We're told a company called celebhotline.com is negotiating for the video. The company's spokesperson, Kevin Blatt told us, "We've seen the tape and we're hoping to close the deal."

We contacted Leighton's rep but so far ... no comment.

The "Real Housewife of New York" (right) and "Gossip Girl's" Zuzanna Szadkowski (common spelling) were spotted together at the Do Something Awards Thursday night in NYC.

How nice of Blair to give her right hand woman a night off.

Rutherford hired the private eye to prove her ex, Daniel Giersch, didn't properly secure the pool and play areas at his home -- which she said endangered the couple's 2-year-old son Hermes. She also wanted Daniel to stop potty training the kid.

Kelly has filed legal papers asking the judge to prohibit Daniel from taking 2-year-old Hermes to his home until he has properly secured the pool and play areas.

She also wants Daniel to stop potty training the kid, stat. She doesn't say why.

The judge has set a hearing for Friday. In the meantime, the judge has ordered Daniel to properly cover the pool.
