Khloe's man Tristan Thompson flew into Los Angeles to visit baby boy, on Friday, and Ms. Kardashian escorted her baller boyfriend, 25, to a late-night rendezvous with the infant at a Beverly Hills hotel.

The 3-month-old baby boy, Prince Oliver Craig Thompson, was driven SOLO by a chauffeur, to meet up with his daddy and Khloe. Tristan looked a bit uncomfortable carrying Prince in his car seat ... well, that's because he doesn't have much practice.

After about an hour together, it was enough googoo, gaagaa, and the baby went back to his mama so Khloe and Tristan could get a bite to eat. After all, cuddling a three-month-old makes a person hungry!
