The hills are alive with the sound of Broadway stars, Gleeks! Now that Rachel (Lea Michele) is gearing up for the biggest audition of her career — her idol, Barbra Streisand’s hit musical Funny Girl girlfriend needs a mentor more than ever.

No, we're not just talking about Will "No One Wants To Marry Me" Schuester (Matthew Morrison). Turns out Rachel's new mentor is a familiar face none other than her onscreen mom, Shelby Corcoran, played by Broadway superstar Idina Menzel!

"Off to #glee tomorrow!" Lea Michele tweeted on March 11. "Rachel's gonna get a visit from a familiar face we haven't seen in a while. And a big audition to prepare for!"

We initially speculated that Lea's muse could be anyone from Jesse St. James (Jonathan Groff) to April Rhodes (Kristin Chenoweth), but we're thrilled to know Shelby is the familiar face in question! She and Rachel haven't been on screen together since Glee's third season, so it's about time they had a mini family reunion plus, did we mention how amazing Idina's voice is?!

"I spy @idinamenzel at #Glee today!" Lea tweeted on March 12th. "So excited to have my mama back!"

We can't imagine that Lea will bomb the Funny Girl audition with Shelby training her (after all, she's a world famous glee club coach!), so expect girlfriend to make her Broadway debut when Glee returns next season. Color us excited!
