Cardi B knows how to finesse her way to her perfect weight—and the method is X-rated.

The “WAP” rapper revealed that having sex is a vital part of her step-by-step plan for gaining back the pounds she lost after battling a week-long stomach issue.

“I need to eat and I need that d–k,” Cardi explained during an April 17 Instagram Live. “‘Cause, you know, d–k helps you gain wait. It’s just a science, you know what I’m saying? It’s a f–king science.”

And while she waits to see results, Cardi shared the other rule she plans to abide by: staying inside the house.

“Until I gain weight back, I’m not going out,” she continued, “because I do not like how my body looks. I look too f–king skinny.”

Noting that she’s currently 130 pounds when she prefers to be around 137, Cardi went on to list some of the ways that being below her ideal weight makes her insecure.

“I don’t feel like pants look good on me or skirts or small little dresses,” the Grammy winner shared. “I don’t like being too skinny.”

This isn’t the first time Cardi—who shares daughter Kulture Kiari Cephus, 5, and son Wave Set Cephus, 2, with estranged husband Offset—has gotten candid about her sex life. She previously confirmed she got “d–ked down” by the Migos rapper, 32, at a New Year’s Eve celebration this past year, despite not officially reconciling.

“The answer to getting back together is not a good night at the club and f–king the night long,” Cardi shared on a Jan. 1 livestream on X (formerly known as Twitter). “We need to work on our s–t. We need to work on our communication. There’s things that he needs to work on, there’s things that I need to work on.”

Noting that the couple—who split in December—are at the point in their relationship where they’re “testing the space,” she added at the time, “That’s why I’m saying that we’re not together until we work out our issues.”

Kelly Clarkson

Yep, the talk show host is standing a little taller these days. Informed by doctors she was pre-diabetic, “I dropped weight because I’ve been listening to my doctor—a couple years I didn’t,” the singer explained to People. “And 90 percent of the time I’m really good at it because a protein diet is good for me anyway.”

She is a Texas girlie after all, “so I like meat—sorry, vegetarians in the world!”

The mom to River and Remington is also enjoying exploring her new life in NYC. “Walking in the city is quite the workout,” she added. “And I’m really into infrared saunas right now. And I just got a cold plunge because everybody wore me down.”

Oprah Winfrey

You get some health advice! And you get some health advice! Because now that the media legend is feeling better than ever, she’s dishing out her best tips. “It’s not one thing,” she stressed to Entertainment Tonight of her treadmill workouts, hikes, water consumption and nutritious eats, “it’s everything.”

While Winfrey hasn’t named the weight loss medication she’s using, she told People in December, “The fact that there’s a medically approved prescription for managing weight and staying healthier, in my lifetime, feels like relief, like redemption, like a gift, and not something to hide behind and once again be ridiculed for,” she explained of adding that particular tool to her arsenal. “I’m absolutely done with the shaming from other people and particularly myself.”

Tarek El Moussa

Living proof that you can, in fact, flip your life, the HGTV personality detailed his two-year fitness journey in a July 2023 Instagram post.

“Sometimes you think you’re doing the right thing but what you actually need is redirection in order to see growth,” he wrote. While his previous regimen included the occasional hot yoga class with wife Heather Rae El Moussa, the reality star noted that he wasn’t following a particular routine, tracking his protein intake or receiving any sort of guidance.

Enter: nutritionist Sean Torbati. Now, “I’m eating the right food & Hot yoga 1-2 times a week which is so good for my mental & physical state,” the dad of three explained. “It all comes down to motivation and perseverance.”

For him, “Once I realized how BADLY I wanted to feel good and be healthy—for myself, my wife, my kids, and my longevity—was the second I put my head down and got to work!!”

Whoopi Goldberg

The View cohost revealed she used Mounjaro—a type 2 diabetes medication—to slim down after gaining weight in 2021.

“I weighed almost 300 pounds when I made Till,” she said on the March 19 episode of the daytime talk show. “I had taken all those steroids, I was on all this stuff, and one of the things that’s helped me drop the weight is Mounjaro. That’s what I use.”

Whitney Way Thore

The reality star knows she’s fabulous with or without your compliments thank you very much. Responding to speculation that she had undergone a dramatic body transformation, the My Big Fat Fabulous Life star responded in a February Instagram post, “I hate addressing this, but no, I have not had medical intervention to lose weight.”

And while she noted she had dropped 100 pounds from her previously 385-pound frame, including 50 after mom Barbara “Babs” Thore‘s December 2022 death, “I weigh 285 pounds and I have been this weight for almost a year now.”

Bottom line, she continued, “Thank you for the compliments, but I really don’t like obsessing over my body and I don’t like it when others do it either.”

Valerie Bertinelli

Well aware that she’s hot in Cleveland, L.A. or wherever else she happens to be, the actress gave her refreshing take on body image with a February Instagram post.

“This is a 150lb body on a 5’4 frame,” the Food Network host wrote, sharing a 2014 bikini photo. “I don’t weigh myself anymore because this is considered overweight by who’s [sic] standards, I don’t know. It’s stupid and I believed them for far too long.”

Fully removed from the pressures of dieting, “I now, finally, know that I am a kind, considerate, funny, thoughtful woman,” she continued. “So please remember, who you are and what your character is, should never be overshadowed by what size you are or how much you weigh. You are enough. Just the way you are.”

As for anyone that might not agree, she summed up, “F–k ‘em.”
