Marianela Pereyra -- the host of NBC's "Poker After Dark" --felt the burn during a workout session in Hollywood this week ... when someone smashed one of the windows of her car and stole her purse.
It all went down at the famous L.A. exercise hotspot Runyon Canyon -- where Marianela parked her car and set off on a good ol' fashioned hike.
But when she finished her workout, Marianela noticed the right rear window of her car had been smashed and her new Michael Kors bag was missing.
The LAPD tells us they are looking into the incident, but stress that people shouldn't leave valuables in plain site when parking their car. Even hot chicks.
