Rihanna reportedly wants new rumored boyfriend Leonardo DiCaprio to go on a diet.

DiCaprio was photographed back in July 2014, while relaxing on a beach in Miami. Daily Mail pointed out at the time that he had noticeably piled on the pounds.

According to OK! Magazine, the Barbardian singer is not content with "The Wolf of Wall Street" actor's currently chubby physique.

"She wants him to get a six-pack," a source revealed. "Ri's got extremely high standards when it comes to who she sleeps with, and Leo falls out of this category because he's a lot more flabbier than her usual lovers."

As a result, RiRi apparently suggested to her beau he should lose some weight and get back in shape. The source claimed that DiCaprio found her advice rather interesting, instead of getting offended: "Leo thinks it's all highly amusing. He's never had a girl tell him what to do, so you can imagine how much he's loving it."

The "Diamonds" hitmaker and the "Titanic" star can make a demanding couple, as the latter also told the former not to get any more tattoos, at least for now.

"Rihanna has always been the type of girl who does whatever she wants, when she wants. She wants a new tattoo on her body, but she's stuck because Leo asked her to promise him she won't let the needle touch her body until she falls in love again," a source told HollywoodLife.com.

Surprisingly, the tattoo enthusiast agreed and decided to follow DiCaprio's alleged demand.

"She's a woman of her word, and she's sticking to that," the source said.

While it may seem like she has totally been whipped, Rihanna is apparently attracted to Leonardo DiCaprio because he plays hard-to-get. 

"He wasn't possessive, and that blew her mind," the source added. "She thinks he's playing some type of mind game with her and she's intrigued by it. Rihanna loves a challenge, and he's unlike the dudes in her past; those were boys. This is Leo, he's something else. He's hitting all the right spots, and I'm not talking between her legs. He's making her feel good and stimulating her on an entirely different level."
