Rihanna on Drake-Chris Brown Drama: Just Crazy!

If Rihanna didn't feel like she was the only girl in the world before this week, the violent nightclub altercation between Chris Brown and Drake - or at least their entourages - certainly could be seen as an ego boost ... or just scary.

She is, of course, Brown's ex and Drake's friend, collaborator, and rumored hookup.

For her part, she was at a different club, with Brown, earlier in the week, but Rih was nowhere to be found at W.I.P. when things got ugly Wednesday.

She heard about it, though, says a source who claims Rihanna "loves this! Men fighting over her? Are you kidding? Of course she loves the drama."

After a deluge of texts telling her what went down, "She just laughed. She's spoken to both of them and just thinks it's crazy. She's glad she wasn't there!"

"She just wants to be friends with both of them."

Clearly they have different ideas. Brown tweeted a pic of a serious gash on his chin after a member of Drake's posse allegedly hit him with a bottle.

Drake has denied "any wrongdoing" through his rep, but Brown and his attorney have pointed the finger at the Canadian rapper and his entourage.

A member of Brown's posse may have been the primary aggressor, however, as reports suggest he was making gang signs and death threats at Drake.

Neither musician is considered a criminal suspect in the incident, FYI.

UPDATE, 6/16: Brown's camp wants to clear the air about one thing.

The R&B star's management, Phase Too Inc., shot down reports that Brown sent a $2,000 bottle of champagne to Drake's table ... a gesture that purportedly prompted him to send back a note to Chris reading, "I am f--king the love of your life."

Phase Too called BS in a Tweet: "There was no bottle sent to @drake and there was no note! Stop the lies, TMZ/MTO!!!! There were no punches thrown, just glass!"

Rihanna hasn't taken a side ... but you can!
