Kardashian Christmas party

 No time like Christmas to reappear!Not only is Kim Kardashian getting her pre-baby body back -- she's already lost 17 pounds since giving birth to her second child, Saint West, with husband Kanye West earlier this month -- but she's back to partying it up, too!

While we're still awaiting Saint's formal social media debut, the 35-year-old reality star made her first post-baby event appearance on Thursday at Kris Jenner's glamorous (and very flashy!) Christmas Eve bash, a party that Kris dubbed the "best night ever" on Instagram.
