She’s set to turn 40 next week but Kim Kardashian reminded her 190 million Instagram followers that age is just a number on Friday.

The mogul shared a new behind the scenes video from a birthday themed photo shoot for her latest KKW Beauty collection which will drop at the exact time she was born next week.

Kim sets pulses racing in the clips where she is seen popping out of her own birthday cake wearing a skimpy bikini top and see-through pants.

The Keeping Up With the Kardashians star posted a few videos from the photo shoot for her birthday collection press box on her Instagram story.

Her coveted figure was on full display in the clips with the beauty wearing a silver bikini with a triangle top that emphasized her ample bosom.

Over the bikini bottoms, Kim sported a shimmering pair of sheer silver leggings which she paired with sky-high Perspex platform heels.

The mother of four struck poses for the camera while she popped out of the top of a giant three tiered birthday cake with white, pink and blue icing.

The best images from the shoot were used for her new Opalescent Collection in honor of her 40th birthday.

‘The Opalescent Collection shades are bold, bright and spirited, and it was important that they could be versatile enough for everyday wear or to layer for a more intense glam look,’ the  SKIMS founder wrote in a recent Instagram. ‘I loved creating this collection and I can’t wait to see the looks you create with it.’

She then noted that the Opalescent Collection launches on her birthday at the exact time she was born – Wednesday, 10.21 at 10:46AM PT.  Opal is the birthstone for October.

An earlier advertisement for the new collection saw the reality TV maven was in a skintight light blue minidress that revealed her hourglass figure.
