Without the luxury of much time to themselves, the 39-year-old star and her banker beau managed to make even reading emails on her phone romantic.

As the JustFab star caught up on what was going on back home, Tim lent his head on his pregnant wife's shoulder.

Finishing up her emails, Kimora interpreted her partner's reading to steal a kiss.

But they better get used to having even less time together, as judging by the fashion designer's rather prominent bump they do no have long to go until she welcomes her fourth child.

It was revealed the star was pregnant in October, but she has yet to talk about her pregnancy.

However, the star proudly displayed her rather large bump in a strapless black one piece as she and Tim relaxed on board.

The couple have been sailing around the Caribbean for over a month, first celebrating Thanksgiving in St. Lucia.

Joining them are Kimora's other children Kenzo, 5 - whom, she shares with actor Djimon Honsou - as well as daughters Aoki, 12, and Ming, 14.

Aoki and Ming's father Russell Simmons has also joined in on the family vacation as, despite their divorce, the hip hop mogul and Kimora remain very close.

Kimora and the Def Jam co-founder were married from 1998 to 2009 and after that she dated Kenzo's father for five years until December 2012, a year later she married Tim.

While an unusual arrangement, Tim and Russell have become friends with the entrepreneur describing his former wife's new husband 'as part of the family'.
