The Goddess of Redheads that is Christina Hendricks.
Also Kat Dennings.

Had a scene with the other girls in Pitch Perfect 2 doing a kinda like Tough Mudder course.

Think Kat had a brief scene in 2 broke girls with minor mess.

It was more Beth (the other girl in the show) that had messy moments lol

You're in luck! She got muddy in her music video "Out of The Woods". It was pretty great, even though it a short scene

Rachel Riley & Amy Dowden

Had an idea in a thread a while back for a movie starting her that ends with her tying up a maxi dress for a tough mudder only for the dress to fall down as she crossed the finish line and she trips on the hem and falls face first into a mud puddle.

She got a little messy in the "Trash" episode of "Firefly":

Rihanna

Kim Kardashian

Pamela Anderson

Selena Gomez has somehow always avoided mess

Never seen that before
Nice

However I would like to see her dunked in a huge vat of mixed condiments whilst wearing latex

Zooey Deschanel

Rachel Riley. Not messy, but soaked. Counts as incremental progress, surely? The ice bucket challenge 2014.

I'm honestly surprised she didn't wind up accidentally wet or messy at some point in New Girl (but I also haven't seen every episode). It seems like everyone else did- Nick in the camping episode, Coach in the teacher conference, feel free to fill me in for the rest.

Re Kim Kardashian- I'll fully admit that I've used the break the internet photo as material by imagining that the sparkles is actually her dress being soaked. If it weren't for the historical significance I would have loved to see her in the Marilyn Monroe dress either gunged somehow or jumping in a pool with it on to celebrate an award.

Aubrey Plaza, pied/slimed. I've seen gossip news that she put together a prank where she invented a fake Pie in the Face tradition where whenever you finish filming a movie in Italy, you're supposed to get pied in the face. Somehow no interviewers ever asked if she got pied.

Alison Brie was on that film, too, but didn't get pied, either, but at least she has those great Community moments--I would have preferred a gooey cool whip or pudding pie for her instead of the shaving foam from that one episode but something something beggars and choosers and all that.

This does count as messy and it's fine if it's somebody's thing, obv, but I'd rather have seen her play a few rounds of rock paper scissors pie.

That's what I get for not watching those tragic late night shows. My second option would have been Kristen Ritter.

Blake Lively!

She has a shower scene in hitchhikers guide to galaxy if I remember rightly

Lana Del Rey

Jenna Fischer

Jenna and John Krazinsky(sp?) did a photo shoot for a magazine having a cake fight. Just google Jenna Fischer and cake, you'll find it.

Molly Qerim from First Take (ESPN)

Say it with me now, folks: Mollie Gallagher!

I say two Spanish celebs, Aitana and Esther Exposito

Martine mcutcheon, Kym marsh, Natalie Pinkham, Georgie Thompson, Emma bunton, patsy kensit

I won't share it because of what it is, but Patsy Kensit had cow dung dropped on her head for Comic Relief in the 90s. Not the kind of mess we want, but I think that counts.

a little bit muddy in her music-video "Out Of The Woods"
