Kelly Osbourne had a $250,000 manicure at the Emmy Awards Sunday night. She wore a black diamond nail polish called Azature to go with her lilac hair and Zac Posen gown.

“'I've been so scared to touch anything because its powdered black diamonds ... [are] worth $250,000. I'm the only person they let wear it, it's in a safe upstairs in the hotel room. I couldn't believe it. I have not touched a thing all day,” Osbourne told E! on the red carpet.

Only one bottle of the 267-carat nail polish was produced, according to the Daily Mail.

The Huffington Post says it is the world’s most expensive nail lacquer. The designer, Azature, said in a press release, “One day I thought, 'Why not showcase this style on nails?' So I developed a Black Diamond Nail Polish with the same attention and quality as my jewelry in order to preserve the elegance of the black diamond.”

Osbourne even posted a picture of the nail lacquer to her Instagram account, with the caption, "I'm [expletive] myself to have that much money on my nails!"

Meanwhile, Osbourne also received attention recently due to rumors she started by telling British television host Alan Carr that she believes Lady Gaga is pregnant, after the ‘ArtPop’ singer gained approximately 25 pounds.

“I think she is pregnant because she has been covering up this part of her body recently, and I have been noticing that a lot. ... And her style has changed and you can’t bleach your hair blonde when you are pregnant,” Osbourne said.

But Lady Gaga dispelled those rumors when she admitted to gaining weight due to her love of “pasta and pizza.”
