There's no denying Lena Dunham lost weight, but now, she's showing off her transformation in a NSFW sketch on Jimmy Kimmel Live!

Lena, 30, joined her co-stars Allison Williams, Jemima Kirke, and Zosia Mamet in "The Golden GIRLS," where the actresses played their famous characters in their later years, while paying homage to the original Golden Girls.

Wearing overalls, a white curly wig, and little else, it didn't take long for the Lenny founder to strip down thanks to a "wet diaper UTI."

“I need to be in bed by 5. By 5:30 I’m going to be dreaming of Tom Hardy licking pudding off his dentures," Lena says as she makes her grand entrance.

Jimmy Kimmel also had a cameo in the parody as a stripper, but not all goes according to plan.

"Mom," the talk show host screamed at Lena before hilariously adding, "Mom, when I'm working, it's Officer Sausage."

Lena then walks completely nude to the refrigerator to grab a slice of cheesecake — reminiscent of the '80s sitcom.

"Well, I'm gonna eat this whole cheesecake in hopes I fall into a diabetic coma so I can forget that my son just came over to show me his member," she says.

While fans are loving Lena's new look, she's not thrilled about the attention her weight loss has received in the media.

"I feel I've made it pretty clear over the years that I don't give even the tiniest of s–ts what anyone else feels about my body. I've gone on red carpets in couture as a size 14," she wrote on Instagram. "I've accepted that my body is an ever changing organism, not a fixed entity — what goes up must come down and vice versa. I smile just as wide no matter my current size because I'm proud of what this body has seen and done and represented."

She continued, "Right now I'm struggling to control my endometriosis through a healthy diet and exercise. So my weight loss isn't a triumph and it also isn't some sign I've finally given in to the voices of trolls. Because my body belongs to ME — at every phase, in every iteration, and whatever I'm doing with it, I'm not handing in my feminist card to anyone."

Get it, girl!
