The 44-year-old performs a water-soaked strip in her undies and gives co-star Jason Sudeikis a lapdance in the flick.
And Jen is not the first screen siren to get her kit off in the name of art.
From Jessica Alba to Natalie Portman, see the stars who’ve played strippers in our photo special.
1) Jessica Alba – Sin City
Jess played a lasso-lashing temptress in 2005 flick Sin City.
On her preparation for the role, she said: “I just work out just to be healthy anyway, so that was already part of it. And I went to strip clubs to see how strippers do it.
“And I realised I wanted a choreographer and Robert Rodriguez said no. I was like, ‘Okay…’ He said, ‘Just feel it. We’re just going to play music and you’re just going to feel it.’”
2) Gina Gershon and Elizabeth Berkley – Showgirls
This filth fest was the most controversial film of 1995. Panned by critics, it nonetheless did rather well as a DVD release for some reason…
3) Rose McGowan – Grindhouse
After directing Jessica Alba in Sin City, Robert Rodriguez next gave Charmed star Rose the perspex heels treatment. She played stripper and lapdancer Cherry Darling in the 2007 film.
4) Demi Moore – Striptease
Demi became the highest-paid woman in Hollywood after taking a $12.5m pay cheque for this 1996 flick. She has said of the film: “Striptease was a huge risk for me. It was difficult for me to do the dancing and the stripping. “While the public perception was hyper-focused on what I was being paid for taking my clothes off, for me it was the intense focus of connecting with my body and myself in a sensual, sexual way, in a way that I’ve never felt before.”
5) Jessica Biel – Powder Blue
Anyone who’s seen this 2009 flick will know Justin Timberlake is a lucky man. His missus Jessica leaves a young Eddie Redmayne speechless as she flaunts her stunning body in this sizzling scene.
6) Marisa Tomei – The Wrestler
Marisa was nominated for an Oscar for her turn as gutsy stripper Cassidy in 2008’s The Wrestler. She too did her research before taking to the stage : “I talked to a bunch of different girls and a bunch of different dancers.
“It wasn’t like I sat and had big interviews with them or anything; we just went out, had some drinks, went to a bunch of clubs, watched a lot of dances, got some dances, brought some guy friends with me, brought some girl friends with me…”
7) Natalie Portman – Closer
Gorgeous Nat never normally strips off in films but she made an exception for Oscar magnet Closer in 2004. Having said that, all nudity was eventually cut from the Mike Nichols flick.
Natalie said: “We made sort of a pact that while we would shoot, we would just do everything and then he cut it the way he cut, showed it to me, saw if I agreed and that’s what happened. “I just didn’t think [the nudity] was crucial to the scene. I thought it was distracting if anything to have it at the head of the scene.” Shame.
8) Kristen Stewart – Welcome To The Riley’s
Kristen revealed a naughty side in 2010’s Welcome To The Riley’s. Researching her role as a 16-year-old stripper in the flick she went to a local strip club – and was promptly offered a job.
She said: “I went to a strip club with the director and the costume designer and it being an odd grouping of people going into a strip club in the middle of the afternoon, I was, like, straight-up offered a job.” The Twilight star also rehearsed hard. She said: “I pole-danced for two weeks. I had bruises all over my legs – it hurts!”
9) Lindsay Lohan – I Know Who Killed Me
10) Heather Graham – The Hangover
Heather has admitted she loved playing sexy stripper Jade in the Hangover movies – because her own life is so dull.
She said: “I’m pretty boring in my real life. I don’t really drink, I’m not that wild, so it’s fun to play these wild characters on screen.”
11) Salma Hayek – Americano
Salma’s got form for exotic dancing – thanks to a mesmerising bikini dance in 1996’s From Dusk Till Dawn.
She also stripped in glasses and pigtails in 1999’s Dogma. So French language film Americano must have been a walk in the park last year. In it, Salma plays a deported Mexican stripper who inherits an apartment in Paris.
12) Agyness Deyn – Pusher
Brit model Agy made her acting debut in Nicolas Winding Refn’s 2012 film Pusher. She said of the role: “She’s a stripper, who uses her body and her sexuality. “I wanted as much reality as I could get. There was so much there in the script, and I read books and watched movies.
“I went to [a strip club] where I watched [someone] and talked to addicts. I tried to do as much as I could to create Flo and what she does, and her little quirks and routines.”
13) Olivia Wilde – Butter
Olivia truly did go Wilde to play a lesbian-kissing, pants-dodging stripper in last year’s Butter.
She clearly enjoyed the gig too. Rumour has it the 29-year-old took fiance Jason Sudeikis to a strip club to celebrate their engagement in March.
14) Halle Berry – Frankie & Alice
Halle played a beautiful stripper with a split personality in this 2010 Canadian flick. She said of the role: “There’s not much research to play a stripper – you just kind of take your clothes off!
“It’s kind of easy!”
We think Sarah Silverman thinks stripping is EASY TOO…:)
