McVitie's heir Jamie got up close and personal with the animals and even got his face painted as a tiger, which appeared to make him pretty happy.
Sharing his adventurous trip with fans on Instagram, party boy Jamie simply said: "Animal." Just look at his grin!
Giving fans an insight into how he spent his day, Jamie soon uploaded a cute video to Instagram showing him feeding a monkey through the enclosure (see video below).
Jamie has just returned home from a two-month trip to New York. He was joined by best friends Spencer Matthews and Oliver Proudlock, as well as his other co-stars to film new spin-off show Made In Chelsea: New York.
Fans are yet to be given a teaser of what happened between the cast in the Big Apple (we're assuming lots of drama!), but they have been treated to a very slick and sultry trailer, where Jamie poses naked!
Made In Chelsea: New York, which will be comprised of six one-hour episodes, is due to air in August.
