Halle Berry and Olivier Martinez are off to Paris with son Maceo for Christmas!

Sorta sad, though -- they left behind Halle's daughter Nahla as they jetted off to the French capital. She's staying in LA with dad Gabriel Aubry.

The former couple have been embroiled in a curious legal battle over their daughter's hair. Halle sued Gabriel to force him to stop straightening and lightening Nahla's hair (in what Halle said was an effort to make her appear more "white"). Well, the Oscar-winning actress won her lawsuit. Why does it matter? Well, read Vogue's editorial on the issue ... the stifling of black identity and straightening, cutting, and braiding of the natural curls that signify African-American-ness is important.

Do YOU support Halle's fight?
