The 21-year-old British actress and 28-year-old American singer are enjoying a luxury getaway to Coco Privé private island resort in the Maldives.
Turner shared a photo Monday on Instagram of herself and the DNCE singer enjoying cocktails on the beach. Turner wore a striped one-piece swimsuit and red cat eye sunglasses.
"Brb. In paradise @cocopriveprivateisland #CocoPrive," she captioned the picture.
The Game of Thrones star also posted a picture on Twitter of herself soaking up some rays by the water.
"[Sun's] out [buns] out at #CocoPrive," she wrote.
Elle U.K. reported Coco Privé costs $45,000 per night. The resort features six private villas, a dedicated staff and access to diving and other water activities, among other luxury amenities.
Turner and Jonas got engaged in October after a year of dating. Singer and actress Hailee Steinfeld said in an interview with the Smallzy's Surgery radio show this month that she played "matchmaker" for the couple.
"Oh yeah," she said when asked if she takes credit for the pairing. "I did get that text from Sophie saying, 'So tell me about Joe.' I was like, 'Go for it!'"
