The E! star flashed a smile for the camera earlier today as she was strutting her famous curves and growing belly in a flowing, brown dress and flats before riding off on a yacht with the rest of her fam.
Kim was put on babysitting duty, watching her nephew Mason during the boat ride while Kourtney Kardashian and Khloé Kardashian Odom had some fun in the waves.
Meanwhile, Kardashian has kept Twitter followers posted (and envious) of her trip by posting multiple photos on the social media website, and even hinted about a video that may surface once the vacation is over.
She tweeted, "Since we are on a family vacay...we need a new song to do a music video to! Any ideas tweeps???"
What song do you think the family chose?! Sound off in the comments!
