The Bachelor star Peter Weber tearfully admits he had a sexual encounter with one of his Season 24 bachelorettes in a new finale preview released by ABC, giving Bachelor spoiler sleuths something new to chew on.

"I don't want this to feel like it's just all about sex, but six days prior I was intimate with someone else," Peter says with tears in his eyes.

It remains to be seen whom Peter was speaking to as well as which bachelorette The Bachelor star allegedly slept with.

However, the brief clip aired after frontrunner Madison Prewett -- the only The Bachelor bachelorette whom Peter has admitted he's "falling in love with" so far on the show -- admits she's a virgin.

"If tonight goes how I hope it goes, I could definitely be falling in love," Madison says during her hometown date. "[But] Peter doesn't know yet that I am saving myself for marriage."

Madison later tells the cameras in the preview of Peter, "If he sleeps with anybody else, it's going to be hard for me to continue to move forward."

One bachelorette can then be heard saying, "You gave him an ultimatum -- and I'm sorry, it's disgusting."

"I think I'm just in shock right now," Kelsey Weier cries.

Next week's The Bachelor episode will feature Peter visiting the hometowns of his Final 4 bachelorettes: Madison, Kelsey, Hannah Ann Sluss and Victoria Fuller.

"I am in love, and I'm really excited for Peter to meet my family," Kelsey says.

Peter apparently hit a bump in the road in his relationship with Hannah Ann after meeting her family in Tennessee.

"[Hannah Ann]'s dad is not going to just give her away to anybody," a woman appearing to be Hannah Ann's mother tells Peter.

Peter then admits to Hannah Ann's father, "I am falling in love with her," to which the stern man replies, "I ask you as a father -- I'd rather you not say that to her."

Peter is then shown asking Victoria F. "for the truth" during her hometown in Virginia Beach.

"Well, it doesn't matter anymore, Peter," Victoria F. replies in tears.

Footage shows Peter raising his voice a little bit and saying, "Victoria, are you kidding me right now?"

"How are we even supposed to move forward from this?" Victoria F. cries. "And you're supposed to meet my family tonight?!"

The promo also featured more twists and turns happening "later this season" in addition to more insight into Peter's unspoiled and highly-anticipated ending.

"Oh my God, I don't even know how to do this. My heart is, like, broken right now," Peter says.

Hannah Ann subsequently vents in tears, "I'm at a loss for words. I just don't know what to do."

"How do you just walk away and give up?" Peter is heard asking.

Victoria F. is then shown walking down the street and yelling, "I'm so f-cking done!"

Finally, The Bachelor host Chris Harrison confronts Peter at what appears to be the Final Rose Ceremony, when Peter was standing with an engagement ring in his hand.

Chris tells Peter -- in a clip viewers have already seen before -- there's something he should know that producers just found out about, and Peter appears devastated and lost after hearing the news.

Peter then has a heart-to-heart with his mother Barbara.

"Don't let her go. Don't let her go," Barbara begs in tears. "This is what love stories are made of, and God has placed her there for you. Bring her home. Bring her home to us."

Based on what was shown of Madison's virgin comments, many The Bachelor fans are now speculating Madison chose to quit the show since Peter had a sexual encounter with someone else and The Bachelor star ended up chasing her down and trying to win her back.

The Bachelor's 24th season currently airs on Monday nights at 8PM ET/PT on ABC.
