mischa barton La Hong Nhut fashion store opening austria

Mischa Barton attended the launch of designer La Hong Nhut's new boutique in Vienna, Austria on Tuesday, and the 26-year-old actress posed for photos with her beau, British actor Sebastian Knapp.

The two have been dating for nearly four months, and since Misch is currently in Ireland starring in the stage production of Steel Magnolias, we're guessing the two have gotten to spend quite a bit of time together. But maybe she wasn't ready for her close up? The former OC starlet looked like a little confused when we snapped her with both Knapp and the designer!
