Stepping out for a day at the race track, Kim Kardashian was on-hand at Las Vegas Motor Speedway in Las Vegas, Nevada on Sunday (February 28).

The E! reality beauty was decked out in a curve-hugging jumpsuit, spending time chatting with press and greeting drivers before the NASCAR Sprint Cup Series Shelby American 350 got underway.

Worn out from a night of partying for her fragrance launch the previous evening, Kim tweeted to her fans and followers, “I feel like I just went to bed, now I’m back up getting ready for Nascar.”

During the race, Miss Kardashian continued to send out messages, tweeting, “Anyone watching Nascar? U guys see the pink Kim Kardashian car?”
