Grab your popcorn for the sh*tshow to end all sh*tshows in "The Bachelor" two-day finale event.

Bachelor Arie Luyendyk Jr. knows viewers are going to hate him after Monday's finale and Tuesday's "After the Final Rose" special. Do you want to know what he reportedly did? It's directly related to who will most likely be named the 2018 "Bachelorette" -- a choice ABC will reveal on Tuesday.

SPOILER ALERT

****

According to spoiler king Reality Steve, Arie picks Becca Kufrin in the finale. They get engaged. But then after a while, he dumps her. Then he starts dating his runner-up, Lauren Burnham. There are unconfirmed rumors that Arie even proposed to Lauren and they are now engaged.

Either way, Becca gets screwed, in an even worse situation than the one Jason Mesnick left Melissa Rycroft. If you'll recall, Jason ended up marrying his runner-up, Molly, and Melissa went on to two seasons of "Dancing With the Stars."

Well, never mind DWTS for Becca. Instead, Steve says she is almost a lock to be the next Bachelorette. But he didn't see the choice of Arie coming as Bachelor, so he added some caveats:

"After seeing what they've pulled in recent seasons and their last minute change ups, it's basically impossible to tell you for certain who it will be. However, everything I've told you since January stands true. I've always said Becca will have all of America behind her, she has the best built-in storyline of any previous contestant going into the "Bachelorette," and the only way she wouldn't get the gig is if she didn't want it. Everything I've been told up to this point has led me to believe she wants it, they've talked to her, they've filmed in MN, and she will be the "Bachelorette." [...]

So the speculation about Tia, Bekah, or Seinne, or even Kristina aren't even in the ballpark. You can't be the "Bachelorette" when they haven't even approached you about it yet. None of those girls are going to be the "Bachelorette." Everything I'm being told is it's Becca, which should surprise no one. We know they've pulled last second change ups in the past, but I really don't expect it this time. I fully expect Becca to be the next "Bachelorette" and filming begins in two weeks on schedule to where it normally begins filming. I even have some of the guys for you which I'll be releasing as we get closer to the first night of filming."

Just don't expect her to take her ex Ross back, if he shows up again:

Apparently Becca was blindsided when Arie dumped her, on camera. Per Steve:

"The second week of January in mid week (Jan 10th on her IG), Becca was in Las Vegas for work. After this Vegas work trip, that weekend was a scheduled Happy Couple with Arie in LA. This was a planned regular meet up, but SOMEBODY, either Arie or producers or both, lied to her and told Becca they were being filmed because they wanted to give the fans an update on their relationship to be shown later. This is when Arie, with cameras in tow, broke up with Becca and ended the engagement. This was the d**k move of the season. So yes, she was pissed and blindsided. At no point did she ever think Arie was going to end the engagement on that meet up, and at no point did she ever think it was going to be filmed doing it."

We're going to be hearing a lot of back-and-forth about the details on Tuesday.

"The Bachelor" finale airs from 8 to 11 p.m. EST on Monday, March 6. "The Bachelor: After the Final Rose" will air over two hours on Tuesday, March 7 from 8 to 10 p.m. on ABC. The Bachelorette will be revealed at the end of Tuesday's episode.
