Mischa Barton took a walk on the wild side on the set of Oasis singer Noel Gallagher's High Flying Birds' new music video in Los Angeles Monday.
The OC alum flaunted her trim stomach and lean legs in a matching leopard-print bra and mid-rise panties set.

"Doing Noel Gallagher's video today. Was so excited I barely slept and he didn't disappoint!" she tweeted.
On the set, the star made sure to stay warm in the unseasonably cool and gray L.A. weather by wrapping herself in blankets, and much to her chagrin, Tuesday's weather was gorgeously sunny.
"How come when you're running around in your underwear it's cold and today it's beautiful?!" she questioned.

Barton, 26, recently turned to stylist June Ambrose for a major style overhaul. Since then, she has been showing off her healthy, slimmed-down physique at several red carpet events.
"I've been running like three miles a day," she told Us Weekly of her current fitness regimen, adding that she also loves juice cleanses and vegan food.
