Middleton, 32, and 6-month-old George traveled to the island of Mustique, and have also been joined by her parents Carole and Michael Middleton, brother James, and sister Pippa and her boyfriend Nico Jackson.
Prince William joined the group last year at the same villa, but unfortunately couldn't make it this time around. "William is staying back in the UK to continue with his Cambridge studies," the insider added to Us. (As previously reported, the Duke of Cambridge, 31, enrolled at Cambridge University for a 10-week program to study agricultural management back in December.)
Middleton and the couple's baby boy won't be gone for long though. They will be heading home "[by the] end of next week," the source told Us. On Feb. 11, Middleton is expected to attend the National Portrait Gallery gala, her first royal engagement of 2014. She will follow-up the event by opening the ICAP Art Room at Northolt High School in Ealing, London on Valentine's Day.
