The 25-year-old posted a number of fun Instagram pics from her night out in Phuket, where the R&B singer was greeted by several species of native animals, The Mail reported.
One of the photos shows Rihanna at Phuket FantaSea, and another appears to show Rihanna with an endangered slow loris - likely on Phuket's Bangla Road.
The slow loris in Phuket has been a long-running issue on Bangla Road, with touts illegally using the endangered animal to solicit money from tourists. While several arrests were made in June, many touts continue to operate, with police saying it is hard to find them because they hide when police show up.
Earlier in the week on Monday (September 16) Facebook fan page Rihanna Thailand posted a picture which seemed to show the Bajan beauty arriving at an airport in Thailand.
It was also stated that she was staying at Sri Panwa in Phuket. However, Sri Panwa have since told The Phuket News that she was not not staying at the property.
Later reports had her booked into a villa at Paresa on the west coast.
Since then Rihanna has posted a number of photos on her Instagram account of her time in Phuket, including many with elephants.
"'They all hail Empress when She walk by,' she tweeted as she got up close and personal with a herd of tame elephants in the street," wrote the Mail.
"The singer appeared to be having a ball in the pictures, that showed her dressed in black pants and a strapless matching top with zipper detail down the back.
"Her dark locks were pulled back into a messy braid, with her face framed by a wispy fringe," gushed the newspaper.
"Large barely tinted sunglasses adorned her face despite it being dark outside and a long gold chain hung around her neck.
"In another snap, RiRi snuggled up to a cute slow loris - a strepsirrhine primate native to South and Southeast Asia.
'"Look who was talkin dirty to me! #Thailand #nightlife,' she captioned the sweet selfie.
"The star also posted a funny shot with her in the foreground and a scantily-clad woman dressed as a possible bride complete with jewelled bikini top and crown alongside a leotard-wearing man - both of whom appear to be yelling at the singer.
"'She was either tryna get married to me, or asking for the rest of my crop over costume! #Thailand #$treetLife,' she explained of the scene."
Rihanna's next gig is in Singapore tomorrow.
