The Kardashians have officially taken St. Barts.

Reality TV's first family might be on vacation, but that doesn't mean they're taking a break from working out. On Tuesday, photographers snapped photos of the family as they engaged in a beachside work out.

Kim Kardashian , who is six months pregnant with her second child, kept cool and bared her growing baby bump, while her sisters Kourtney and Khloe worked up a sweat in the water with a personal trainer.
