We already know that our girl Rebel Wilson is all in for "Pitch Perfect 2," and we've even seen little microsnippets of Fat Amy's grand return in the trailer for the movie, but not much beyond that.

MTV News finagled a little big more detail, including the fact that Wilson has a "big solo to myself" in the upcoming sequel. Eeeee!

At a press day for the upcoming "Night at the Museum: Escape From the Tomb,"

Wilson told MTV News everything she possibly could -- and the threat is very real.

"Elizabeth Banks might kill me if I say what it is," Wilson said of her solo, which is "an old classic" song.

Wilson has already seen the movie, and says the musical numbers, comedy and stunts are bigger and badder than ever.

"We made it for the fans of the movie and I think they're not going to be disappointed," she said.

And what about those "Ghostbusters" rumors? Wilson has been one of the names most commonly rumored amongst contenders to star in Paul Feig's all-female "Ghostbusters" movie.

She didn't say yes, but...she didn't say no, either? So keep that hope alive!

"I just feel so lucky that there's so many opportunities on the table right now, so we'll see," Wilson said.
