Beyonce and Jay-Z are introducing baby Blue Ivy to the ultimate playground for the rich -- St. Barth!

The 3-month-old is already racking up the miles in the private jet and earning beaucoup VIP points for her luxury travel ... the family rented one of the most expensive private villas on the island to accommodate Blue, the nanny, the family and their entourage.

Talk about a silver spoon! That's one lucky baby!
