Prince William, his pregnant wife Duchess Kate and her parents have flown to the Caribbean for a holiday.
The Sun said the 31-year-old duchess has recovered from her morning sickness.
The 30-year-old prince and Kate are staying at a villa on the island of Mustique.
Their luxury pad boasts a pool, games room and stunning views of the Caribbean Sea.
Kate's parents Michael and Carole Middleton are staying nearby.
"The duke and duchess have joined the Middletons for a winter break," a source told the daily.
"Both William and Kate were hoping her condition would not stop her from making the eight-hour flight to Barbados and the connection to Mustique."
"A month ago such a journey would have been unthinkable for her, so this is a clear sign she has made a virtual recovery."
The royal couple have enjoyed six holidays on Mustique since they started dating.
