Faith Hill and Jo Dee Messina tread carefully whenever they're in the presence of BROOKS + DUNN because the country duo love to terrify the singers with their scary pranks.

Kix Brooks, 50, and 52-year-old Ronnie Dunn get a huge thrill out of irritating their fellow country music stars - and they're particularly proud of two pranks they recently pulled off.

Brooks says, "Faith Hill pulled something on one of our friends, so we bought an eel at a truck stop and it mysteriously ended up in her bed in her hotel.

"We've kind of regressed from there. Jo Dee Messina put balloons on our bus one time. So we hired a hot air balloon, put a sack over her head and sent her on her way. Just so happened that she was scared of heights."

Dunn adds, "It also happened that the balloon crash-landed in a neighbourhood in DC. She was p**sed, and that was good. You want to p**s them off."
