Mischa Barton may play a voracious slutmonster on The O.C., but she's kept her clothes on while doing so. But behind those golden highlights and that bratty personality lies a generous soul, and Mischa cleverly gets around that whole FOX "no nudity" thing to show a little snoob during some R&R at a spa.
Mischa and her secret-fat-guy-in-waiting boyfriend, oil heir Brandon Davis, enjoyed their one-year anniversary at the Bacara Resort Spa in Santa Barbara. You can always count on Brit tabloids to get the money shot, so thank you, Daily Star, for capturing Marissa's mammary for posterity.

And high-res, for all you Photoshop snob pervs.

And if that's not enough, you can check out Mischa's nude review at MrSkin.com.
