Rihanna 'dumps' Drake for cheating with sexy Instagram groupie? Chris Brown's ex ousts Drizzy as a player, 'b*tches they lying' [PHOTOS]

Some fans consider Rihanna and Drake the "perfect couple" - but is Drizzy still too much of a flirt to be in a commited relationship?

UPDATE: Rihanna 'dumps' Drake after Instagram cheating scandal? Couple 'couldn't be happier' amidst break-up RUMORS

Rumors suggest that just over the weekend, the Nothing Was the Same rapper flew a sexy Instagram groupie out from Texas to join him in Toronto. RiRi was left behind in LA:

And this isn't the first time Drake's "shaded" Rihanna for another girl - and now the "Pour It Up" songstress has allegedly finally had enough.

An "insider" tells the infamous gossip webloid MediaTakeOut.com:

"Drake is such a FRAUD. He tells you all kinds of things to make you think he's so sincere... and the next thing you see him on [MediaTakeOut.com] with some big booty heaux... I can't believe that [Rihanna] fell for his bullsh*t. She really liked that FOOL."

Want more proof that RiRi's over Drizzy's mind games?

Just take a look on Instagram.

One diehard Rihanna fan (who goes by kareemfenty on the popular social networking site) updated their "bio" to read:

"Aubrih has risen once again and it ain't falling unless I get caught giving Papi head️."

This fan reached-out to the Barbadian beauty, asking what she thought about the update:

And RiRi's response?

Ouch - did Rihanna just oust Drizzy's "playboy" status on Instagram? Or is she just calling-out this fan for their rather inappropriate headline?

What's up with that?
