But luckily only for a 5-episode guest spot!
Sources say that she's still taking dance lessons from choreographer Tyce Diorio and has even hired a private singing coach to prepare her for the role. They add:
“Katie is finalizing a deal to join the cast for a limited story line next season. Katie’s film career has stalled, and she’s desperately needs a career boost. She’s hoping a stint on Glee will jumpstart her standing in Hollywood.”
Or just ruin Glee all together. Either way, we're not too sure about this!!
