Alexis, 42, kissed her man's cheek next to some majestic elephants in the Asian country.
She also posted a snap of them holding onto one another while walking on a dirt road.
Alexis and Andy have been in Thailand for several days now.
She's rumored to be joining another popular Bravo show, Below Deck. Alexis teased her return to reality television shortly before she, Andy and a group of friends made their way to Thailand on Friday, March 15.
It would make sense for them to be on Below Deck. Their friends who are with them have shared several pics on board a luxurious yacht over the past two days.
Alexis hasn't been on reality television since she departed RHOC in 2013. She was part of the show for four straight seasons.
