Moments after Jasmine Waltz was fingered as David Arquette's alleged rebound chick ... the 28-year-old just happened to be photographed leaving a hotel in  West Hollywood last night.

As we previously reported, sources close to Arquette tell us he started seeing Waltz after he and Courteney Cox decided to take a "trial separation."

Jasmine is no stranger to the paparazzi -- she's been linked with all sorts of male stars ... such as Ryan Seacrest ,Chris Pine and Jesse McCartney.
