Grammy-winning singer Rihanna may, indeed, be off of musicians for good as new pics of her and Hollywood stud Leonardo DiCaprio have emerged.

Pics of the now-rumored couple at the Playboy Mansion this past weekend are floating online.

It wasn’t Leonardo DiCaprio’s birthday this weekend … but it sure felt like it … he was seen going straight up “Wolf of Wall Street” on Rihanna at the Playboy Mansion. It’s a good thing for Leo … designer Nikki Erwin had boyfriend/producer Chuck Pacheco — “Alpha Dogs,” “My Sister’s Keeper” — invite him to her star-stacked 30th B-Day at the Playboy Mansion Saturday … and our spies tell TMZ, Cap and RiRi were gettin’ super steamy and even swapping spit.

Recent reports suggested RiRi was calling it quits on dating musicians.

Rihanna has sworn off bad boys for good, according to a new report. The S&M hitmaker, who has been enjoying Christmas in Barbados, has told her pals that she won’t be hooking up with anyone from “the industry” after failed romances with Chris Brown and Take Care rapper Drake. RiRi is reportedly fed up with getting her heartbroken after trying (more than once) with both of the musicians. (The Mirror UK)

Young Money’s Drake and RiRi were spotted chatting away in a New York City nightclub last year.

So Drake and Rihanna walk into a club … which means they were banging, right? The former couple hit up Griffin nightclub in NYC Monday night … and according to photogs they were there for nearly 2 hours and left at around 3 AM — 21 minutes apart. Eyewitnesses inside the club tell TMZ … Drake and Rihanna had tables next to each other and were deep in conversation, flirtatious and whispering in each other’s ears. (TMZ)

Drizzy previously cleared up widespread speculation of allegedly dissing RiRi at his OVO Fest concert last August.
