The Bachelorette comes to a close on Monday night, with JoJo Fletcher choosing between Jordan Rodgers and Robby Hayes. ET has been with Fletcher for every step of her journey. So, who will she choose -- and how did she make the big decision?

In March, at her very first photoshoot as the Bachelorette, the 25-year-old reality starlet (in a red sequin dress, of course), and described her perfect man. "I would just want someone who is genuine and makes me laugh and is my best friend," she said. "And ultimately, at the end of the day, someone who is going to love me as much as I love them."

As fans know, it has come down to former pro football player Rodgers and former swimmer Hayes. I was with Fletcher on her very first group date (that pun-packed fire academy training), and interestingly, back then, she told me her three frontrunners were Rodgers, Hayes and Luke Pell.

After the show's Men Tell All taping on July 16, I reminded Fletcher of that moment, and she said that must mean going with her gut is the right thing to do! But as for what the final decision comes down to, she wouldn't get into specifics. "It's a really hard day," she said. "A lot happens in that day; so many different emotions!"

Her third and fourth finalists, Chase McNary and Pell, both told me they think she'll choose Rodgers. "She looked at him kind of in a way that was different than a lot of the other guys," Pell said. McNary said the "connection" between the pair had been clear ever since Fletcher gave Rodgers the first impression rose.

We'll also see Fletcher's somewhat famous family Monday night -- for the first time since her mom's hilarious champagne-guzzling incident on the hometown dates of The Bachelor, and where her brothers got a little confrontational with Ben Higgins. "[My family] will probably have opinions," Fletcher told me with a smile at the time of the first photo shoot. "But I value those opinions."
