Kim Kardashian set pulses racing as she took part in a sizzling ʙικιɴι pH๏τoshoot while promoting her SIMS simwear collection.

The reality star, 42, showcased her famous curves in the skimpy black two-piece as she posed next to a luxury sports car.

The media mogul put on a leggy display in the snaps and added height to her frame with a pair of black heels.

Also wearing a pair of black sleeves, the mother-of-four complimented her look with large sunglᴀsses.

Wearing her platinum blonde locks in a poker straight style, Kim accentuated her natural beauty with a light palette of makeup.

It comes after Kim announced the return of her SKIMS swimwear line, just in time for Spring Break.

The Keeping Up With the Kardashians star narrated a video while standing in front of racks of the swimwear line.

She said: ‘OK guys I am so excited to announce Skims swim is officially coming back. I know you’ve asked for it for a long time now.

‘We have all of our signature colors – we have 27 styles launching – and we have a lot of brand new swimsuits and cover-ups and even accessories.

‘And we have these two new colors the turquoise and the neon green, it’s our biggest swimwear launch ever.’

‘The sleeveless zip is one of my favs I wear it as a bodysuit with pants or to swim,’ she concluded.

The KKW Beauty mogul wore a grey one piece, zip neck swimsuit in the clip.

Earlier in the day, Kim donned a long, platinum blonde wig and a tiny turquoise blue SKIMS ʙικιɴι and flaunted her famous curves in a promo for the swimwear line.
