At first glance, Jason Oppenheim's vacay pics with his model girlfriend make ya think there's "Selling Sunset" baby news coming, but upon closer inspection ... they're just hot and horny!!!
Jason and Marie-Lou Nurk are yachting around Mykonos with fellow 'Sunset' star, and Jason's ex-GF, Mary Fitzgerald and her husband, Romain -- and, for some reason, Jason decided to plant some kisses right on MLN's belly.
But, we're sure the universal sign for "we got one in the oven" is misplaced here, because other shots show Marie-Lou vaping ... and also, Jason later got a massive handful of her ass. Not exactly giving maternal instincts or parent-to-be vibes!
