She was recently spotted in the club, smooching the cheek of a guy named Justin LaBoy. Now, photos have surfaced online of RiRi getting cuddly with a girl while hanging out in Miami.

The friendly female-in-question goes by the name "King @_Heartthrob1" on Twitter. Her profile reads:

"Focused lesbian. Proud little of celebrity hair pro /image consultant (Yusef Williams) and Rihanna's Personal Hairstylist (ready for my future)."

And here are some of the "suspicious" tweets she sent out last week... many of which have since been deleted:

@__Heartthrob1: "Tryna decide which overseas show I'm gonna fly out to see @rihanna again hahaha... My brother is gonna be like oh gosh, lol."

@__Heartthrob1: "I met and hung out with @rihanna now I just gotta get @SkyDigg4 love me some them : )."

@__Heartthrob1: "If y'all phuck'd a celebrity would y'all tell everybody?? Lol."

@__Heartthrob1: "@Soul_for_Soles I know... but I honestly can't help it yo we had our moments."

@__Heartthrob1: "I miss @rihanna she smells so good grrrr... Every girl in the world should smell like @rihanna I miss you

Photos of the two girls partying have since been deleted from @__Heartthrob1's Twitter page, but they can still be viewed here.

When the tweets started going viral, several RiRi fans confronted the songstress' new "party friend" - and she fought back:

@AliCat816: "@__Heartthrob1 not hating but if @rihanna was gon mess wit a stud she gon be a fine 1. You lookn hella thirsty lyin on her."

@__Heartthrob1: "@AliCat816 I didn't do that and 1 she wasn't sittin on my lap 2 she wasn't in Miami that was Tampa show they are phucking lying... know what you talking bout before you talk my bro works with her I didn't do that s#it."
