NBC’s “Hairspray Live!” Wednesday night played to the lowest ratings of any of the network’s live musical specials.

Trade reports Thursday said the adaptation of the Broadway production, based on John Waters’ 1988 film about a Baltimore TV dance show in the early 1960s, was seen by 9.045 million viewers and scored a 2.3 rating and an 8 share in the coveted 18- to 49-year-old demographic. A rating is the percentage of TV-owning households who watched. A share tells what percentage of those households that are then watching TV are watching a particular show.

The previously least-seen of the NBC live musicals was “Peter Pan Live!,” airing December 4, 2014, to 9.13 million viewers and a 2.4/7 ratings/share in the same demographic. The network began airing a string of live musicals in 2013 with “The Sound of Music Live!”

While stars Ricki Lake from the film and Marissa Jaret Winokur from the 2000s Broadway production made cameo appearances, Nikki Blonsky, from the 2007 movie musical, did not. The Great Neck native, 28, posted on Instagram Wednesday, “Congrats to the cast of @nbchairspraylive on a job well done from myself and the rest of the Hairspray Movie Cast!”

Also taking to social media was singer-actress Jennifer Lopez, 47, who stars in NBC’s next live musical, “Bye Bye Birdie.” “Loving #hairspraylive !!!!” she tweeted during the telecast, followed by emoji of hearts and ‘60-style flip-curls.
