The fourth season of the 'Bachelor' spinoff was being filmed for a summer air date.

ABC has halted filming on the upcoming new season of Bachelor in Paradise.

"We have become aware of allegations of misconduct on the set of Bachelor in Paradise in Mexico," Warner Bros. said Sunday in a statement. "We have suspended production and we are conducting a thorough investigation of these allegations. Once the investigation is complete, we will take appropriate responsive action.”

The fourth season of the ABC reality series had recently begun filming and is slated to premiere Aug. 8.

The summer series reunites former castoffs of The Bachelor and The Bachelorette at a resort in Sayulita, Mexico, in hopes they find love with other stars of the franchise. ABC had announced the first round of the Bachelor in Paradise cast last week. The 16 men and women who had begun filming included two runner-ups from previous seasons, two returning Bachelor in Paradise stars and four villains, including Corinne Olympios from Nick Viall's season of The Bachelor and DeMario Jackson, a recent castoff of Rachel Lindsay's The Bachelorette.

Blogger Reality Steve (Steve Carbone) posted a photo of many of the show's stars that was snapped by a fan at the airport in Puerto Vallarta, saying the cast was being told only that they were being flown to Houston.

Carbone, who has long posted spoilers about the show, initially named two contestants who were reportedly involved in the incident but later deleted the tweets after media coverage indicated that a crime may have been committed.

Though the initial cast list has been announced, more familiar franchise faces were set to join the Chris Harrison-hosted spinoff and would be announced at a later date. The cast of BIP shuffles each week, with a handful of contestants joining the dating competition throughout to shake up existing relationships and form new ones. Last year's cycle ended with three engagements, though only one couple (Carly Waddell and Evan Bass) is still set to walk down the aisle.

Most of the cast has yet to comment, save for contestant Robby Hayes who took to Twitter on Monday to say, "What happens in paradise, stays in paradise. #NoComment #BIP4."

On June 3, Bachelor creator Mike Fleiss announced that filming on the season had begun by posting a picture of Harrison on set in Mexico, along with a photo of the show's resident bartender, Jorge.

The Bachelorette, which is currently airing, returns next week and won't be new Monday due to the ongoing NBA Finals.
