Kourtney Kardashian is always quick to lend her sisters a helping hand... or any other helping body part!
The "Keeping Up With The Kardashians" star did her little sister, Kim Kardashian a solid by stopping down to her skivvies on January 20. She showed off her sensational figure in a matching set of black shapewear by SKIMS. Kim has been going through a tough time with her alleged inevitable divorce to Kanye West and Kourt figured a little product promotion could cheer her up. When sales go up, so do attitudes!
