The ultimate family affair! A very pregnant Kim Kardashian and her family enjoyed some sun and quality time together aboard a yacht during their getaway to the Greek island of Mykonos on Saturday, Apr. 27. The reality star, 32, helped to keep an eye on nephew Mason, 2, toting him around the large vessel clad in a loose brown cover-up.

Sister Kourtney, 34, had her hands full with baby Penelope, 9 months, who she carried around the yacht while clad in a deep-cut black swimsuit.

"Since we are on a family vacay…we need a new song to do a video to!" Kim tweeted early Saturday morning. "Any ideas tweeps?" The reality star later shared a few snapshots of the view from what looked to be the family's villa and ship.

"Heavenly," she captioned one photo that she shared from step-brother Brody Jenner's Instagram account, showing a clear blue infinity pool disappearing into a deep blue ocean.

Also on hand for the Grecian holiday are mom Kris Jenner, sisters Khloe and Kourtney, Kendall and Kylie Jenner, Kourtney's love Scott Disick and their two children Mason and Penelope. Kim's boyfriend Kanye West did not join in on the family vacation.

One day earlier, the pregnant mother-to-be showed off a rare glimpse of her growing baby belly while taking a stroll around the family's villa, using a camouflage-patterned sarong to cover bits of her bump. Kim completed her look with her hair pulled back in multiple braids.

Prior to the group's 10-day vacation, Kim spent some quality time with West, 35, in New York City, where the pair packed on the PDA, holding hands as they strolled through the Big Apple.
