(In a similarly landmark turn, Brandy played Cinderella in the 1997 TV movie, costarring Whitney Houston as her Fairy Godmother.)

Asked how she was celebrating the awesome career coup, however, Palmer told Vanity Fair on Friday, “I don’t really celebrate. And besides, I still don’t believe it is real!”

Hmm, that last part sounds like over-the-moon enthusiasm to us! And of course, she may have celebrated since then.

The Just Keke host’s debut will be Sept. 9 so of course she will be spending the next month—a period of time that includes her 21st birthday—rehearsing.

Palmer will be replacing Cindy Paige Faure in the role of the titular heroine who goes from family servant to (spoiler alert) Prince Charming’s see-through-footwear-rocking bride over the course of a few hours.

Carly Rae Jepsen originated the role when the musical premiered to the masses back in March and took her final bow in June. 

Growing up, Palmer told VF, she “always had an idea to approach Broadway for an audition.” Similarly, when asked by Broadway.com back in 2012 if her love of singing combined with her love of acting included a desire to perform on Broadway, Keke said, “That would be really fun.”

In addition to scoring her own BET talk show, Palmer also recently appeared on the small screen in Showtime’s Masters of Sex and the Emmy-nominated Lifetime movie The Trip to Bountiful.
