Spandex

Even though Kim Kardashian looks fantastic, it seems the 33-yearl-old wasn't kidding when she recently admitted she has 'about 10 pounds to go' off achieving her desired post-pregnancy body.

On Sunday, the reality star was seen once again hitting the gym for a gruelling workout.

Only this time it was a case of work hard and play hard as she was accompanied her friend Blac Chyna for a day of pampering after her gym session at The Beverly Hills Hotel.

Kim looked like she meant business as she marched ahead of her friend, dressed head to toe in workout gear.

Talking about gaining weight whilst pregnant, Kim recently admitted that she found the experience 'hard'.

'Everyone was really not the nicest with me when I was pregnant, and in my mind ... you lose sight for a second, like, 'Wait, what if I never get my body back to normal again?''

But Kim clearly hasn't wasted any time in getting back in shape.

Her legs looked toned in the tight black spandex tights, and she paired the leggings with an expensive pair of black and white trainers her weekend workout.

Chyna wore a long red fright wig and construction boots, and didn't leave out her signature diamond cheek studs.

The friends drove from the hotel to the salon in Chyna's $125,000 new Mercedes G-500 SUV.

Kim's little sister, Kylie Jenner, was given the same model of car in August for her 16th birthday.

Chyna, a former stripper, is in a relationship with rapper Tyga.

The couple now has a son, King Cairo Stevenson, and are engaged - as are Kim and Kayne.

The gal pals - who met through their rapper fiances - also took a break from pressing mommy duties on Friday when they went shopping at Neiman Marcus in Woodland Hills.

Although the two might appear a little mismatched, they seem to be getting along.

And spending time away from the Kardashian clan and with a fresh face might be what's in order for Kim.

With her mother, Kris, in the middle of a breakup with husband Chris Jenner and sister Khloe filing for divorce from basketball player Lamar Odom last week, the Kardashian household seems to be full of chaos.
