Leonardo DiCaprio has reportedly forbidden his rumored new girlfriend Rihanna from getting 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.

So what is tattoo enthusiast RiRi's final decision? The source claimed that she has 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 Rihanna has totally been whipped, the "Pour It Up" singer is apparently attracted to "The Wolf of Wall Street" actor because he is playing hard to get. 

"He wasn't possessive, and that blew her mind," the source said. "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."

Meanwhile, an In Touch source, via HollywoodLife.com, revealed that the Rihanna wants to bring DiCaprio home to Barbados to introduce him to her family.

"Rihanna doesn't bring a guy home unless she really likes him. This is a sign she adores him," an insider said. "She's always thought he was cute. She loves his look, his sweet smile and his little nose."

The insider added that although the couple's affairs have been private, their close friends and family are aware that "they're seeing each other."
