Gaga recently owned up to peeing in dressing room bins, and Jessie said she too likes to relieve herself in places other than the toilet.
“I read about Lady Gaga. But I wasn’t surprised. I wee in cups all the time,” she told the Daily Star.
“When you are a female artist and your day is filled with Press and promo, you have to master pi**ing in a cup – or a bin, apparently.
“I’m not so much of a diva that I have someone to hold the cup, but a few unfortunate people have had to dispose of it for me.
“Sometimes we just put it next to an apple juice to see if anyone drinks it.”
Meanwhile the Do It Like A Dude singer said she’s looking forward to her new role as a mentor on the UK version of The Voice alongside Black Eyed Peas star Will.i.am, singer Will Young and Welsh crooner Tom Jones.
“The Voice is going to be amazing. I’m shi**ing myself but in a good way. I can’t wait to meet Tom Jones. He’s Tom Jones, after all.
“I’ve never met Will Young before, either, so that will be cool. I’m a big fan of them all, which is a good job because it would be horrible if I didn’t like any of them.
“I’ve met Will.i.am briefly and can’t wait to get started.
“I’m really happy that I’m the only girl on the panel.”
