Kim's disappearing act! Kardashian looks thinner than ever as she visits her favorite cosmetic doctor again

Kim Kardashian looked incredibly skinny as she paid yet another visit to her favorite cosmetic doctor's surgery on Saturday.

The 35-year-old reality star flaunted an extremely trim waist and flat tummy in a workout ensemble of tight black leggings and low-cut stretch top.

And in profile, her fashion choice confirmed her remarkable weight loss with her thighs and even her famous derriere appearing much slimmer than of late.

Kim chatted away on her phone after driving herself to the offices of Dr. Simon Ourian where, just three days ago, she had undergone skin-tightening treatment and a 'nonsurgical tummy tuck'.

And this week she's been raving about the size of her waist that had visibly shrunk as she pursued her goal of reaching 120 pounds after giving birth to two children.

The Keeping Up With The Kardashians beauty who is married to Kanye West credits strict adherence to the Atkins Diet and a workout regimen for her weight loss.
