Coco, 38, took to Instagram to share photos and video of the epic swim, which seemed to, naturally, make her pretty nervous.
"One of the highlights while in Bahamas has been swimming with the sharks!" the TV personality wrote. "I know what you're thinking.. I watched that TV show, 'When wild animals go wild' too but these guys acted like dogs."
She said that the sharks were very "friendly," adding, "Plus the rush of doing something crazy is half the fun. I even got Chanel to come in with me!"
