Why Renee Graziano Wasn't Impressed by Amber Portwood on 'Marriage Boot Camp' (Exclusive)

In TooFab's exclusive sneak peek at Friday's season premiere, Portwood's now ex-fiancé turned a casual run-in with Graziano into a meet and greet. First impressions mean a lot to Graziano, because the fan-girling resulted in her throwing some shade their way.

The trio first crossed paths as they arrived to the house, with Portwood and Graziano exchanging hugs and words like "honey" and "baby" as they said hello. But Baier broke the "Act cool around stars" code by offering up a handshake to Graziano and gushing, "I'm Matt. I'm a huge fan." He also admitted, in a confessional, that they both love her show.

Though Graziano kept her cool in person, commenting that there are some "big attitudes in this house," she later dissed them talking to the camera. "F-ck, the 'Teen Mom,'" she said. "I didn't come here to have fans. I would've f-cking went to Madison Square Garden if I wanted fans."

Sparks definitely flew during filming, though it's unclear who Renee butted heads with the most.

"There was difficulty in the house, there was difficulty. And everyone will see it," she told Us Weekly on Tuesday. "No one will say, 'Oh she's picking on them,' everyone will see the difficulty in the house."
