Beyonce Enjoys Crazy Yacht Diving

Beyonce isn't even living life on the edge anymore ... she's going right over it!

We got these shots of Bey and Jay Z balling out off the coast of Sardinia on their rented super yacht, the Halo. Yes, the Halo. But instead of sunbathing or sipping bubbly ... Beyonce decided to go all daredevil and dive off the top deck.

Looks to be at least a 30-foot drop, and we think that's Jigga recording video from below. Maybe she was inspired by the Olympics ... or maybe she's making a quick escape.

Bottom line ... #CakesintheOcean
