The “Frozen” favourite says, “It’s exhausting but I’m also like, ‘Oh you’re developing a sense of comedy, I love it.'”

She goes on to say of one prank in particular, “I was making dinner, they were being nice to each other, I knew something was wrong,” before adding they then asked to cuddle in bed before going to sleep.

Bell reveals how once she pulled back the covers, “they have dumped easily a gallon of water onto my mattress.”

“It was saturated, and tucked into the sheets, they also put pumpkins and a bunch of their dirty underwear. They are spitting up they’re laughing so hard.”
