Some celebs prefer sunning in St. Barth for the holidays, while others prefer skiing in Aspen ... and frankly, we love both!

We spotted a pregnant Kimora Lee Simmons on her ex-hubby Russell's yacht in St. Barth, sunning and snacking in the Caribbean heat. While Mariah Carey and Melanie Griffith choose Aspen as their annual Christmas destination.

The recently-separated ladies strolled the village streets, shopping -- Melanie with her daughter Stella and Mariah, with some friends.

The singer sports some strange ruffled bell-bottom pants over her snow boots but despite us not loving her fashion choices, we do LOVE her radiant smile! Looks like she's keeping spirits high, even after splitting from hubby Nick Cannon. It's her first Christmas alone with the twins Moroccan and and Monroe, but even if they don't get to see daddy, at least Santa will pay a visit!
