Casey Wilson is laughing off reports that she was fired from Saturday Night Live for being too fat.

"I had an amazing time on SNL, and these rumors are completely untrue," Wilson, 28, tells PEOPLE in an exclusive statement. "And to clarify, the issue isn't that I'm too fat, it's that I'm too phat. Can I get a WHAT-WHAT!"

Earlier this week E! online reported that the curvy SNL star – who joined the cast in 2008 and spoofed celebrities such as Rachael Ray and Jennifer Aniston – got the boot after producers demanded that she lose 30 lbs. over the summer and failed to do so.

A rep for the show tells PEOPLE, "there is absolutely no truth" to the reports.
