Kim Kardashian smoldered as the blonde bombshell when she was seen with her newly bleached hair worn down on Instagram Stories on Thursday.

The girlfriend of SNL veteran Pete Davidson hinted to her fans that she was working on a secret project that she was 'excited' about but was not able to reveal.

'You have no idea what I am doing today,' cooed the lingerie designer and makeup mogul as racks of clothing could be seen in the background.

'I'm really excited,' she finished as she zoomed in on her face with a filter that added pointy ears and freckles to her flawless face.

It is likely she is doing a photo shoot for her new Kim Kardashian makeup line which is being re-branded after she stopped production of KKW Beauty.

The name of the line could be SKKN as she has filed a trademark for that name, according to a report from TMZ, but she was given a cease and desist order over the moniker last year.

This comes after she spent 10 hours bleaching her raven locks while worrying some of the tendrils were going to fall out.

Kim had dyed her hair a platinum blonde color to go with her Met Gala gown, which was the $5million beaded number Marilyn Monroe wore when she sang Happy Birthday Mr President to John F Kennedy on stage in 1962.

The dress was on loan from Ripley's Believe It Or Not which had purchased the iconic gown at auction.

Kim made an appearance on half-sister Kylie Jenner's YouTube vlog released on Wednesday as she expressed concern over losing her hair after bleaching it for 10 hours.

Kylie complimented Kim for how 'bold' she was for dying her hair platinum blonde as Kim nervously replied: 'I'll risk getting my hair to fall out.'

Prior to Kim's grand entrance in the hotel room, the 24-year-old Kylie Cosmetics mogul was seen putting on her now much talked about Off-White wedding dress outfit.

Kylie spots her big sister and tells her: 'I cannot believe you're really dyeing your hair.'

Kim tells Kylie's four-year-old daughter Stormi she was aiming to look like the main character in Disney's Frozen as she said: 'My hair's gonna be blonde like Elsa!'

Her younger sister praised the middle Kardashian sister as she said: You're so bold for that! You're so bold.'

Kim replied: 'Oh I've been doing this for 10 hours already. I'll risk getting my hair to fall out.'

The star revealed she forced herself to lose 16lbs in just three weeks in order to make it fit. 

Marilyn's glittering beaded gown was designed by Jean Louis, and has been on display at Ripley's Believe It or Not! Museum in Orlando, FL, after they bought it from Julien's Auction for $4.81million. 

Marilyn - who died at 36 from a drug overdose in 1962 - is said to have paid $1,440 for the custom piece to the designer, and it holds the record for the for the most expensive dress sold at an auction, making it one of the most expensive dresses in the world. 

Legend has it that the garment was so tight, Marilyn had to be sewn into the dress prior to her performance for the President.

Kim had the same struggle when she discovered the dress didn't fit her, and began to cry when she learned that the dress could not be altered. 

The ex-wife of Kanye West told Vogue how she went on a ruthlessly strict diet deadline in order to slim down and wear the dress to the Met. 

'I would wear a sauna suit twice a day, run on the treadmill, completely cut out all sugar and all carbs, and just eat the cleanest veggies and protein,' she told the outlet. 'I didn't starve myself, but I was so strict.'

Marilyn's unique hourglass figure and exact measurements have been debated for decades, but one dress maker claimed she was 5'5" tall, with a 35" bust, 22" waist, and 35" hips. Her bra size was said to be 36D.

Kim once said of her own measurements: 'I am a size 27 jeans… My measurements are 38, 26, 39. But remember I am 5'2″ and 1/2 and everyone carries their weight in different places.'

Kim is said to have left her hotel on Monday covered up in a dressing gown, and had barricades set up outside of her hotel to make sure no one saw the outfit before her red carpet appearance.

When she got to the Met Gala, there was a secret dressing room set up for her near the steps where a conservationist from Ripley's met her to help fit the dress, who was wearing special gloves.

Kim even said that she didn't wear any body makeup, as she usually would do at such an event, in order to preserve the dress.
