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.
Dude knows where his bread is buttered, and also how to butter it!
