Lily James flaunted her incredible toned abs as she let fans in with some behind-the-scenes snaps from Pam & Tommy.
The beauty is starring in the Disney+ series and has shown off some photos of herself getting into character.
The 32-year-old paraded her chiselled tummy in a white furry crop top as she portrays pin-up Pamela Anderson.
She sported tight black leather trousers in the photo - and even wore a pair of prosthetic breasts.
Pam & Tommy, which was released earlier this month on the streaming platform, recounts the infamous release of a sex tape made by Pamela and then-husband Tommy Lee on their honeymoon, in the 1990s.
Another snap showed the actress wearing a pair of blue jeans and a grey jumper as she looked into the mirror.
Lily took to Instagram to show fans what she had been up to.
Writing on top of the photo, she thanked the show's makeup artists, hairdressers and stylists.
She wrote: "@kammylennox @barryleemoe @momeinhart @mabbymakeup knocked it out the park with this look."
Fans may love it - but according to reports, Pamela isn't totally pleased by the series.
Pam & Tommy has been accused of "re-opening a wound" for the former Baywatch beauty, a source in America has claimed.
After the premier of the show in America on Hulu, a TV insider told People: "There's a sense that the show is re-exploiting Pamela.
"After the tape was made public, it was a very traumatising situation and it's unfair that she is being re-subjected to this trauma, like re-opening a wound."
"Pamela deserves a level of respect. She's a human being and a mom. There's a sense of hypocrisy about it. It's her life and she should have the decision [as to] whether it's turned into a commodity for public consumption."
The miniseries stars Lily as Pamela, Sebastian Stan as Tommy, Seth Rogen as Rand and Nick Offerman as adult film producer Milton Ingley, who Rand contacted to get the tape out into the mainstream.
Pam and Tom tried to prevent the tape's release by suing the distributor, Internet Entertainment Group.
Eventually a confidential settlement was reached but the tape was still released publicly.
