Ex-King Constantine of Greece has recently recovered after heart surgery, and if his son's pals are correct, the former monarch will have more to celebrate very soon.
Thirty-nine-year-old Prince Nikolaos will pop the question to his long-term girlfriend Tatiana Blatnik before he turns 40 next summer, his friends believe.
Nikolaos, the third child of Greece's former king and Anne-Marie of Denmark, began dating event planner Tatiana five years ago.
The couple currently live in London's Chelsea where the prince works for his father in the royal's private office.
"We're expecting them to announce their engagement soon," one of the prince's friends reveals.
"Tatiana has even been taking Greek lessons so that she can speak to her future in-laws in their native tongue,"
