The latest photograph, the third in as many days, has added to growing intrigue over whether the princess has been released from house arrest by her billionaire father, the all-powerful ruler of Dubai.
Princess Latifa, 35, has not been seen in public since a failed attempt to flee Dubai in March 2018.
In the latest Instagram post, Princess Latifa sits beside Fiona Day, who describes herself online as an intuitive consultant and a psychic medium.
On Sunday, two images that appeared to show Princess Latifa with friends in shopping malls in Dubai were posted on Instagram.
The royal’s health and well-being is the source of global speculation.
“I’m a hostage,” the sheikha said in one video.
“This villa has been converted into jail.
“I can’t even go outside to get any fresh air.”
Sheikh Mohammed has always insisted the claims are baseless and that his daughter has full freedom.
Last month, the United Nations said the United Arab Emirates (UAE), which is made up of seven emirates, including Dubai, had failed to provide compelling proof that Princess Latifa is still alive.
Former UK Foreign Office minister Peter Hain has urged Boris Johnson’s government to intervene and find answers from Dubai.
“These photos are very far from that.
“Why is she not allowed to speak directly to journalists for instance?”
In 2018, Princess Latifa attempted to escape from Dubai, risking her life to flee the palace under the cover of darkness.
But just days after she was smuggled out of the UAE in the boot of a friend’s car, as she was on her way to India to start her new life, the boat she was travelling in was raided by commandos.
It is alleged they dragged Princess Latifa at gunpoint off the boat and forced her to return to Dubai against her will.
The dramatic would-be sea escape and its aftermath intruded into the carefully controlled image maintained by the family of Sheikh Mohammed, who is believed to have several dozen children from multiple wives.
Some of his sons and daughters figure prominently in local media and online, but others are rarely seen.
Sheikh Mohammed is the founder of the successful Godolphin horse-racing stable and on friendly terms with Britain’s Queen Elizabeth II.
In 2019, he received a trophy from the queen after one of his horses won a race at Royal Ascot.
