Jessica Biel finds eating in the shower "deeply satisfying".

'The Illusionist' star has opened up about her love of "shower eating" and insisted she wants to start a "movement" for anyone who is juggling too many tasks at home - with Jessica even sharing her key rules to successfully scoffing snacks while washing.

In a video posted on TikTok, Jessica said: "I'm just so thrilled everyone's so interested. I really want to start a movement. A shower eating movement for people who are multitasking it's just going to be such a huge relief in so many ways."

She went on to explain how to manage shower eating - insisting a ledge for food containers is "helpful" and warning her followers to keep their mouth closed while chewing.

Jessica added: "Here are my rules for shower eating. A ledge is really helpful. Something you can stick your cup, your yoghurt container, your coffee, your espresso, whatever it is you are enjoying.

"But I like to take a bite or a sip and put it on the ledge and then you do your thing. You wash your hair - keep the soap out - that’s a big deal. It's pretty simple guys, you can do this. I find it deeply satisfying."

Jessica - who has two kids with her husband Justin Timberlake - went on to explain she struggles to keep her mouth closed in the shower but it's very important while eating and washing at the same time.

She added: "The only tricky thing is when you’re chewing, you got to keep your mouth closed because I still like to get under the water while I’m chewing, and for whatever reason, I want to open my mouth at the same time and spit water.

"I don't know if that's a childhood squirt gun situation, a deep rooted need to spit water in the face of someone. Maybe just because I get spit in the face with water all the time by my kids so I'm just ready at any moment to retaliate."

She concluded by saying: "There's the pro tip. Chew, do not open the mouth [and] do not let the shower water in. There you go, enjoy your shower-consuming."
