Here they are ... newlyweds Serena Williams and Alexis Ohanian chillaxin' on an insanely expensive private island in the Bahamas during their honeymoon -- that they booked on Booking.com.
We're told the villa runs $35k per week -- and you can only get to it if you have an aircraft or a boat.
The photos of S & A at the villa were taken by a drone but we're told the couple willingly participated in the shoot in connection with Booking.com ... so, it wasn't a crazy rogue paparazzo invading their privacy.
