Looking good Mischa Barton!

The actress, 30, showed off her toned tummy in a white two-piece swimsuit in a photo she posted to Instagram on Sunday. She topped off her look with a hat and a long, open, star-print cardigan.

“Rocking my girl @valemicchetti’s hat. Sunny Cali,” Barton posted along with the photo, taken in Malibu.

This isn’t the first time Barton has flaunted her physique on social media.

In July, the former The O.C. star shared a topless photo from Greece.

“Island vibes #Mykonos #Censored,” she captioned the sexy snap.

Barton – who has struggled with her weight and body issues in the past – credits her stint on Dancing with the Stars with helping her to get back in touch with her body.

“I’ve noticed a difference in my body,” Barton wrote in her PEOPLE blog in March. “I don’t think I’ve lost weight, but I can feel my body opening up, and I just feel more in tune with my muscles.”
