The buzz about Jennifer Lopez's 'Bye Bye Birdie'

It's a year away, but folks are already talking about Jennifer Lopez's starring role in NBC's "Bye Bye Birdie Live!"

The superstar will appear in the network's latest live production franchise, set to air in December 2017.

Lopez teased her role Wednesday night as NBC aired "Hairspray Live!"

"I am SO excited to be a part of NBC's next live musical #ByeByeBirdieLive!" the singer-actress tweeted.

But the reaction is divided.

On one hand some hailed the casting for its diversity after it was announced in October.

The Latina will portray Rose "Rosie" Alvarez in the musical set in the 1950s about a rock 'n' roll star who gets drafted. Chita Rivera made the role famous on Broadway.

As the news has sunk in some are questioning whether Lopez is up to the rigors of singing live.

Yet some fans are excited about it.

NBC Entertainment Chairman Robert Greenblatt said in October that Lopez approached the network with the idea to put on the musical.

"Broadway musicals and films fueled my childhood and 'Bye Bye Birdie' was one of my favorites," Lopez said in a statement at the time. "I'm proud to be a part of the NBC family with 'Shades of Blue' and I thought it would be a blast to take on one of their big live musicals."
