No, that's not a photo of Kim Kardashian with a brand new tramp stamp. It's Naya Rivera!

The "Glee" actress has been slowly transforming into the reality TV star for some time now -- and today, she took the next step by showing off her bikini booty. 

Clad in a floral two-piece, Big Sean's ex-fiancee put her perky behind on display on Instagram, the latest in a series of revealing swimsuit photos she's taken while on vacation.

That's definitely one way to distract us all from the rumors she was fired from (or at least had her role reduced on) the Fox musical series after clashing with Lea Michele on set. 

Rivera's reps deny the firing, and Naya herself offered only this as an explanation on Twitter:

"Whether it's in school, home, or all over the Internet lol. Hold your head high, stay true to yourself, and know you are loved!"
