Newly-minted Playboy model Lindsay Lohan just arrived at court for her probation progress report -- and she means business ... dressed like a boob-shy librarian in a buttoned-up cardigan and slacks.

Behave.

An engagement ring Roman Polanski gave to Sharon Tate before she was murdered by the Manson family in 1969 has been auctioned off ... and TMZ has learned it raked in more than $21k.

The ring was surrounded in controversy -- with Tate's sister insisting it wasn't Sharon's "official" engagement ring -- but rather an "unofficial symbol of her relationship" with Polanski.

The auction house later produced a letter signed by Polanski, contradicting Tate's sister.

The controversy didn't seem to matter when the ring hit the block at the GottaHaveRockandRoll.com auction -- because the item sold for $21,260 ... well over the $10,000 starting bid.

So far, the identity of the big winner has not been revealed.

Although she once claimed to be a lesbian, controversial singer Sinead O'Connor celebrated her 45th birthday by marrying a man for the fourth time at a drive-thru wedding in Las Vegas yesterday.

Wearing a demure tattoo-revealing low-cut pink gown, Sinead walked down the aisle back of a Cadillac with fiancé Barry Herridge, 38, at the notorious Little White Wedding Chapel -- the same spot Britney Spears said I do to Jason Alexander in 2004.

As the happily married couple exited the chapel ... no one threw ripped up pics of the Pope.

Queen Elizabeth couldn't keep her usual stoic composure and cracked a rare smile upon meeting some wigged out judges in London on Wednesday.

Not sure what to wear while in NYC on Monday, adorable 11-year-old Willow Smith decided to put on everything in her closet.

All Kardashian women may not be created equal ... but one of the biggest nail polish companies on the planet is sure paying them like they are ... and get this -- even the half-sisters are raking in BIG MONEY.

TMZ has learned ... all 6 K-ladies (Kris, Kim, Kourtney, Khloe, Kylie and Kendall) inked a deal with OPI back in March to become spokeswomen for a Kardashian line of nail polish ... featuring colors like:

Sealed with a Kris -- an intense dark red tone
Kim-pletely In Love – a soft, delicate pale pink hue
Khloe Had a Little Lam-Lam – an eye-catching dark emerald hue
Listen to Your Momager! – a striking deep blue tone

According to the contract, obtained by TMZ, the family was guaranteed $600,000 up front -- plus a cut of the nail polish profits.

Here's the thing ... the documents show the money is being divided EQUALLY between all of the women -- that's $100k-per-gal for all you math wizards out there.

Shocking considering Kim is in her own stratosphere when it comes to star-power ... then again, they say charity starts in the home.

Look closely ... WWE diva Kharma's new engagement ring is actually two in one -- a ring ... ON A RING -- and TMZ has obtained a pic of what might be the coolest piece of jewelry ever forged by man.

Sources close to Kharma -- real name Kia Stevens -- tell TMZ, the diva's fiance popped the question a few months ago ... and with a rock like that, it's no surprise she said yes.

No date for nuptials has been set ... but we're told Stevens (left) -- currently on maternity leave from the WWE -- is planning to tie the knot in June.

The Kardashian Klan only has eyes for themselves ... and that's why the family is threatening to take legal action against a woman who wants to use the family name to sell an eyelash-elongation product.

The product is called KardashianLash (a kind of eyelash-growing make-up thing) and the person behind the company -- named Sarah Ehrlich -- just filed a petition to trademark the name.

We spoke to Ms. Ehrlich -- who tells us, she wanted KardashianLash to help raise money to send Honduran orphans to cosmetology school (a worthy cause) ... and she didn't think the K's would mind.

Italian fashion designer Robert Cavalli definitely enjoys the finer things in life ... like having his sexy younger Russian girlfriend become his personal suntan lotion applier in Miami on Thursday.

Nice to see the 71-year-old still uses protection.

Just when you thought "Twilight" fans had a healthy grip on reality -- TMZ has learned, lady Twihards are invading bridal boutiques, secretly lying about being engaged ... so they can try on a replica of Bella's wedding dress from the new flick.

The $799 replica is being sold in Alfred Angelo bridal boutiques everywhere -- and people who work at the chain tell us the scheming fans are driving them crazy, making it extremely difficult to conduct business.

By the way, we really don't think Twilight fans have a healthy grip on reality.

Wearing a form fitting white bandage dress, Christina Aguilera showed off her stunning talents at the AMAs last week, while Kelly Clarkson belted out her hits in a copper colored version on "The X-Factor."

Question is ...

"Inglourious Basterds" star Diane Kruger went old school in a pair of high waisted granny panty bikini bottoms in Mexico this weekend.

Lady Gaga’s super high-cut dress at the International Emmys Monday night in NYC was this close to exposing her little monster -- but TMZ has learned, it wasn’t made that way.

A rep for the designer -- Stéphane Rolland Haute Couture in France -- tells us, the asymmetrical frock came straight off the catwalk ... meaning it was intended to be worn by a model much taller than Gaga.

According to the rep, “The slit came way further up her waist than what our designers had in mind."

Dressed for an S+M funeral, Lady Gaga rocked a black sheer lacey dress thing in NYC on Tuesday -- while Jennifer Lopez kept it a little classier in a more modest version at the AMAs on Sunday.

Question is ...

Here's Jennifer Lopez, 42, gettin' sick on the floor in a sparkling nude bodysuit at the AMAs last night (left) -- and a 22-year-old Britney Spears back in her infamous barely there outfit from her "Toxic" video in 2003 (right).

Question is ...

Doing his best Kenny G impersonation, adult contemporary singer/songwriter Jason Mraz rocked some curly longer locks and chin bush at an event in Australia last night (left) -- quite a change from his more groomed and clean-cut bikini look of a couple years ago (right).
