Amber Tamblyn is channeling her inner Donald Trump.

The 33-year-old actress performs Color Me Badd's classic, "I Wanna Sex You Up," on Spike's Lip Sync Battle, and dresses up as the 70-year-old Republican presidential nominee. Tamblyn is battling her Sisterhood of the Traveling Pants co-star and close friend, America Ferrera, in the upcoming episode, and gyrates on her during the 1991 jam.

In a preview, Ferrera -- as well as hosts LL Cool J and Chrissy Teigen -- obviously can't hold it together during Tamblyn's performance, bursting into laughter when the actress starts thrusting into Ferrera's side. Tamblyn sports a red tie, a suit, and an obvious fake tan as she busts out a few '90s dance moves, including a pretty amazing running man.

Tamblyn and Ferrera's lip sync battle airs Wednesday, Oct. 19, at 9 p.m. ET/PT on Spike.

While Tamblyn's Lip Sync Battle appearance is obviously lighthearted, the actress wasn't joking when she told a horrific sexual assault story earlier this month after Trump's leaked 2005 conversation with then-Access Hollywood host Billy Bush. Trump was heard saying lewd comments about women, including that he needed some Tic Tacs in case he started "kissing" Days of Our Lives actress Arianne Zucker, whom the two were en route to meet for Trump's guest appearance on the soap.

"You know I'm automatically attracted to beautiful -- I just start kissing them," Trump said. "It's like a magnet. Just kiss. I don't even wait."

"And when you're a star, they let you do it," he added. "You can do anything."

Tamblyn -- who's been married to comedian David Cross since 2012 -- penned a graphic personal essay on Instagram in response. The actress recalled attending a show with some friends in Hollywood shortly after ending "a long emotionally and physically abusive relationship," when her ex spotted her in the crowd.

"The minute he saw me, he picked me up with one hand by my hair and with his other hand, he grabbed me under my skirt by my vagina -- my p**y? -- and lifted me up off the floor, literally, and carried me like something he owned, like a piece of trash, out of the club," she wrote. "That part of my body, which the current Presidential Nominee of the United States Donald Trump recently described as something he'd like to grab a woman by, was bruised from my ex-boyfriend's violence for at least the next week. I had a hard time wearing jeans. I couldn't sleep without a pillow between my legs to create space."

"I am afraid my mom will read this post," she continued. "I'm even more afraid that my father could ever know this story. That it would break his heart. I couldn't take that. But you understand, don't you? I needed to tell a story."
