Last year, when his hit "Don't Ya" went No. 1, Brett Eldredge kept his promise and went skydiving, and this time he promised to swim with sharks without a cage after his song "Beat of the Music" went to the top of the chart.

Brett told "People:"

"Getting past the fear of breathing underwater was the first step.  But when you get to the bottom it's peaceful and quiet.

"Our second dive was to a beautiful old shipwreck, and sharks were everywhere.  The people who ran it told us the sharks are curious and would be swimming all around, but respect them and be smart and we'd be fine.  I decided right away to be smart!"
