Celebrity Beauty Splurges: Beyonce's Gold Manicure And Other Extravagant Beauty Treatments

It seems like everything Beyonce touches lately turns to gold, but the Super Bowl singer may be taking this Queen B thing a bit too literally – even down to her fabulous fingers.

In a new promotional video for the Mrs. Carter Show world tour, Knowles dresses up in theatrical Victorian garb – complete with crown and sceptre – grinning at the camera in the ostentatious, queenly costume.

The wildest part of the over-the-top look? Bey’s H&H-designed manicure, which reportedly cost $900 – or about $90 bucks a nail.

While most of us wouldn’t dream of spending that kind of cash on our fingernails, Bey’s costly talons don’t even come close to making our list for most indulgent celebrity beauty expenses.

In fact, $900 is a positively meagre price compared to the $250,000 black diamond manicure Kelly Osbourne wore at the 2012 Emmys.

That’s right: $250K on nails.

When it comes to ridiculous celebrity spending, Kelly and Bey are in good company: from fingernails to facials, we've rounded up some of the most outrageous star beauty splurges.

You know what they say – it really does takes a village (or rather, the price of a small village) to keep up appearances in Hollywood.

Rihanna Spends $23,000 A Week On Her Hair

Rihanna is almost never seen sporting the same hairstyle twice. From mohawks to flowing locks, RiRi's love of variety means she spends over $23,000 a week on a personal hair stylist -- that's more than a million dollars a year!

Mila Kunis Requests $7,000 Ruby Facials

Even seemingly down-to-earth starlets love to indulge. Mila Kunis reportedly likes to keep her skin looking fresh with a HD Diamond and Ruby Peel -- a facial that uses precious stones to buff away skin impurities and costs $7,000 a pop.

Jennifer Lopez Glows, Thanks To $1,000 Placenta Cream

J.Lo's famous glow costs her $1,000 a week in human placenta facials. It may seem kind of gross, but proponents swear that the vitamin and protein-rich smearing placenta encourages skin regeneration, making your face baby-smooth!

Madonna Buys $78,000 Anti-Cellulite Device

It's no secret that The Material Girl lives lavishly, especially when it comes to her rigorous beauty regime. Madge reportedly purchased an at-home anti-cellulite machine for $78,000 that uses acoustic wave therapy to eliminate unsightly skin dimples.

Serena Williams Takes a $5,000 Evian Bath

Serena Williams revealed just how serious she was about soaking when she christened the world's most expensive bath at the Hotel Victor in Miami Beach. The exclusive 'Evian Experience' comes filled with spa treatments and 1,000 litres of natural Evian spring water -- as well as a $5,000 price tag.

Celine Dion's $2,000,000 Humidifier

When Celine Dion demanded a humidifier for her Las Vegas hotel room, no regular humidifer would do -- the Canadian singer requested a $2 million machine to keep her vocal chords warm and to prevent the Vegas climate from drying out her skin.

Kate Middleton's Bee Venom Facials

To keep her skin royally radiant, Kate Middleton reportedly indulges in bee venom facials, which (you guessed it) use bee venom to keep skin supple and youthful.

One ounce of venom costs approximately $55,200 to extract; Victoria Beckham and Gywenth Paltrow also swear by this odd beauty treatment.

Demi Moore Beautifies With Blood-Sucking Leeches

Demi's ever-youthful appearance didn't come cheap -- she's rumoured to have spent over $400,000 in plastic surgery! -- but it seems the 41-year-old actress will go to any extremes for beauty, including having blood-sucking leeches 'detoxify' her blood. Riiight.

Kelly Osbourne's $250 Thousand Diamond Manicure

Kelly's 2012 Emmys look achieved Internet fame after she posted an Instagram photo with the caption, "About to get a $250k manicure..."

Kelly received a ton of backlash for the ridiculously extravagant manicure, but the reality star was ultimately unrepentant, Tweeting, "...please forgive me for not regretting it. It made me feel like a queen!"
