Leo DiCaprio + Rihanna + The Playboy Mansion = ?

Just like many other weekends, Leonardo DiCaprio was at a party at the Playboy Mansion this past weekend. But this time was different; Rihanna was there too. Reactions are mixed as to what happened between the two of them. TMZ reports that a witness saw the two of them making out, while DiCaprio's friend denies the hookup. Either way, everyone can agree that there was some heavy duty flirting going on, and the two did end up at the same after party.
