Jeremy Meeks and Chloe Green's Baby Enjoying the Yacht Life

Jeremy Meeks and Chloe Green's baby boy is already living in the lap of luxury -- the perks of having a billionaire grandpa.

The "Hot Felon" and the Topshop heiress were spotted on a mega yacht Tuesday, off Turkey ... and we got our first good look at their newborn son, Jayden. The yacht -- named Lionheart -- belongs to Chloe's dad.

We're told Meeks' older son, Jeremy Jr., was also aboard the vessel. As you'll recall ... he got primary custody of Jr. in a deal he struck with his ex-wife, Melissa, in June.

Once the kids were away though, Jeremy's attention turned back to his hot baby mama ... and her booty.
