We know who is leaving Glee after next season. But now we have major scoop on someone who will be returning:

Deadline Hollywood reports that Idina Menzel is nearing a deal that would bring her back to the show as Rachel's mom - for up to 12 episodes!

Menzel originated the role of Shelby Corcoran on season one. No word yet on just how or why she'll return, but it's safe to assume Shelby will play a significant role in Rachel's post-high school plans.

"I'm really excited the that Idina is joining the family again," said Ryan Murphy. "We missed her last year and we're happy that she is coming back."

We agree! This gives us hope that season three really will focus on character development, as various Glee spoilers have teased.
