Tony Award winner and Hollywood legend Bernadette Peters will appear on the new NBC series “Smash” as the mother of one of the aspiring Broadway starlets, Ivy Lynn. News about the guest spot hit Broadway blogs last week, but many Twitter fans who tuned into the show tonight just found out after the show ran a teaser.

“Smash” star Katharine McPhee also tweeted the news, and “Bernadette Peters” is now a trending topic:

She plays Ivy's mom! Great casting! #SMASH RT @KayleighVerno: Bernadette Peters on @SmashTheSeries next week! Can this get any better?!?!

Reaction was…dramatic:

When I saw the Smash promo and Bernadette Peters is on next week I started to cry. #nowijustcryfornothing

If Bernadette Peters was really Ivy's mom, there's no question she'd get the Marilyn gig. Who would dare piss off la Bernadette? #Smash
