After attending a live Q&A for the show Wednesday, the singer flew Down Under for some fun in the sun and made a new friend along the way.
"I wanted to take him home with me!" she wrote Thursday on Instagram, sharing a photo of her and a koala. "Thanks to the Currumbin Wildlife Sanctuary and their amazing work."
In addition to mingling with the country's furry residents, Carey also hit the beach – where she showed off her impressive bikini body.
But the trip proved a quick one, as the star shared another Instagram photo of a Hawaiian rainbow on her way home that same day. Carey will kick off the latest season of Idol on Jan. 16.
