Joe Jonas and Sophie Turner on a luxury yacht in Mexico

They announced their engagement in October 2018, after one year of dating.

And on Thursday, Joe Jonas and Sophie Turner continued to enjoy spending some time away from the spotlight as they soaked up the sun aboard a yacht in Mexico.

The Jonas Brothers singer, 29, and his Game of Thrones love, 23, put on a very racy display as Joe applied sun tan lotion to Sophie’s pert derriere.

The beauty is letting off steam after her popular TV show Game Of Thrones – in which she plays Sansa Stark – had its season eight premiere on Sunday.

The blonde star looked sensational in a black swimsuit, which was covered in pretty white hearts and featured a cowboy style belt, highlighting her slim waist.

Sophie shielded her eyes with a pair of angular black sunglasses and further accessories her look with a smattering of mixed-metal jewellery.

Her long dishevelled tresses were left to hang down around her shoulders and the talented star appeared to be make-up free for the boat day.

Joe spent his time relaxing in a pair of navy, cream and red swimming shorts, leaving his toned torso on display.

A full day’s charter aboard the lavish yacht – named Bad Romance III and part of the Azimut line – costs a whopping $4,000.

Billed as providing an ‘unforgettable experience’, Bad Romance III is certainly fit for two A-listers, with champagne, snorkelling and spectacular sunset views on the itinerary during the full day at sea.
