Robert Pattinson 'flirts' with Eva Chow, Kristen Stewart romantic reunion over? [PHOTOS] 'Twilight' heartthrob parties with fashion designer, K-Stew films 'Anesthesia' in NYC

A few weeks ago, it appeared that Robert Pattinson and "Twilight" ex-girlfriend Kristen Stewart were MAYBE getting back together. As Mstars previously reported:

Robert Pattinson and Kristen Stewart 'talk all the time,' getting back together soon? 'Twilight' ex warns R-Patz 'Don't Play Christian Grey' in 'Fifty Shades of Grey' movie

But apparently R-Patz still enjoys living the single life, and he doesn't plan on taking this K-Stew "romantic reunion" too seriously. Especially now that Stewart's filming her new movie Anesthesia over in NYC while Pattinson stays in LA.

The 27-year-old British heartthrob recently attended a celebrity-studded fashion party honoring Givenchy creative director Roccardo Tisci and famed fashion photographer Marcus Piggott. The duo posted a slew of party photos on Instagram on Tuesday (Nov. 12). Several of these snapshots featured a smiling R-Patz, who appeared to be having an awesome time (sans Stewart).

In one picture, R-Patz was spotted chatting-up fashion designer, Eva Chow. The two looked to be having a great time while  innocently flirting.

mertalas: "Rob & Eva ! What a night!"

No biggie, the two are probably just good friends, but still... R-Patz is really taking advantage of the single life!
