Rihanna celebrated her 27th birthday this weekend, and in typical RiRi fashion, it was just the slightest bit over-the-top—particularly when it came to the guest list.

According to People and Us Weeklythe party—which took place at businessman Jim Goldstein's home in Beverly Hills—was attended by Beyonce, Jay Z, Mick Jagger, Naomi Campbell, Bill Murray, Russell Simmons, Paris Hilton, Jim Carrey, and of course, Rihanna's alleged boyf, Leonardo DiCaprio

In fact, rumor has it that Leo actually helped throw the bash, which went past five in the morning on Saturday—though there are mixed reports regarding the ultimate judger of relationship legitimacy: How closely they were dancing. 

Via Us's source, Rih and Leo "were dancing close all night." But, as per People's spy, "They weren't couple-y but they would flirt and dance so definitely a little magic there. They were definitely flirty and dancing, but not over the top." What does it mean?

Also at the party: balloons that spelled out R-I-H-A-N-N-A and a three-tier cake decorated with leopard print and marijuana leaves. Though we aren't sure of the cake's flavor, we can only imagine there was plenty of "magic" involved.
