As previously reported, Rumer Willis is joining the cast of 90210 this fall in the role of Gia.

A lesbian that works at the West Beverly Blaze, Willis' character is only appearing in one episode.

But that doesn't mean her future co-stars can't look forward to the guest-starring stint. Said Shenae Grimes to People:

“Rumer Willis is joining us for a little while. I’m not sure for how long, but we are very excited."

Meanwhile, Grimes also shed a bit of light on her character in season two. It looks like Annie's new dark side will cause her to be an outcast, at least for awhile.

“[There's] kind of a big twist this year. I’ll start out on a different foot then I did last year. I’m not part of the gang for a little while and you’ll see why,” the actress said.
