Fox announced the news Tuesday afternoon in a statement released to ET, and explained that the pre-taped episode would be swapped out for another episode recorded
"Tonight’s previously scheduled episode of Beat Shazam featured a guest appearance by Demi Lovato," Fox stated. "In light of recent reports, we have decided to replace the episode of Beat Shazam with another all-new episode. Our thoughts go out to Demi and her family."
Meanwhile, Lovato's upcoming concert at Atlantic City Beach in Atlantic City, New Jersey, has been canceled as well.
Lovato was scheduled to perform in New Jersey as part of her Tell Me You Love Me World Tour. The 25-year-old artist recently returned to the States following the European leg of the tour, which lasted over a month.
LiveNation, the event promoters for the tour, confirmed the cancellation to ET on Tuesday.
"Demi's Atlantic City appearance on July 26 has been canceled in light of today’s news," the company said in a statement. "Tickets will be valid to attend the Lauv performance on July 26th along with The Chainsmokers show on July 29th as part of the Atlantic City BeachFest Concert Series." The added that refunds are also available to ticket holders.
Lovato's tour is set to go on hiatus following Thursday's show, before continuing through Latin America on Sept. 20, with a performance at the Mexico City Arena. The tour was originally set to conclude on Nov. 27, with a show at Centro de Eventos do Ceará in Fortaleza, Brazil.
Demi Lovato Hospitalized For Apparent Drug Overdose (Report)
There's no word yet on what impact, if any, her hospitalization will have on the remaining tour dates, or her scheduled appearance at a benefit concert in Toronto on Sunday, which is not part of her world tour.
ET has reached out to LiveNation for comment regarding Lovato's scheduled performances.
TMZ initially reported that Lovato appeared to have suffered from a heroin overdose -- however, the publication later put out a second report from a source claiming the singer did not OD on the drug. According to the outlet, she was treated with Narcan -- an emergency treatment for narcotic overdoses -- at her home in Hollywood Hills, California.
The singer's rep later released a statement and an update on her condition, saying, "Demi is awake and with her family, who want to express thanks to everyone for the love, prayers and support. Some of the information being reported is incorrect and they respectfully ask for privacy and not speculation as her health and recovery is the most important thing right now."
Lovato has been open about her past issues with substance abuse. Last month, she dropped a surprise track called "Sober" about relapsing. She had been sober for six years when rumors started to swirl about her relapse, leading to the surprise release of "Sober," in which she apologizes for letting down herself, her family and her fans.
A sources previously told ET that Lovato's relapse occurred at some point in between the North American leg of her tour, which ended on April 2 in Newark, New Jersey, and her European leg, which started in Belfast, Ireland, on May 24.
"I was just really proud of her that she was honest, because it's really hard to be honest with yourself," Azalea told ET. "So, to be honest with the whole world, [to share] something that you struggled with very publicly, it's something that is very admirable."
