Kelley was also noticeably absent from The Bachelor: The Women Tell All taping, which raised eyebrows, and then she was one of only several women from Peter's cast of bachelorettes to make an appearance onThe Bachelor's live finale that aired on March 10.
In addition, Barbara recently declared Kelley her "fave" and asked the attorney in her Instagram comments to join her for a day of lunch and shopping soon.
So was -- or is -- there something going on between Peter and Kelley, whom the pilot had randomly met at a hotel shortly before filming even began?
"I have heard that. I heard that I'm pregnant and I also heard that I'm with Peter right now," Kelley told E! News. "I'm not with Peter."
Kelley assured the website, "I promise I'm not dating Peter. I'm not dating Peter."
Kelley, in fact, claims she has no idea why The Bachelor producers even chose to invite her to Peter's finale. However, she said she's "grateful" for the chance to watch The Bachelor ending unfold live.
"I got to experience something that -- I didn't know how it worked. I was like, 'Well I'll sit in the stands and figure out what's going on here too,' like, 'Let's see how all this happens," Kelley explained.
"It was kind of hard to hear at times so I didn't really like hear too much of it because the speakers weren't the best. Um, but it was dramatic."
Kelley added, "There was times where my mouth dropped and there was times where I was gasping."
The live finale on March 10 featured Peter dumping Hannah Ann not long after he proposed marriage to her at the Final Rose Ceremony in Australia. (Peter only seemingly popped the question, however, because Madison had quit the competition after meeting his family).

Peter told Hannah Ann during their breakup he couldn't give her his whole heart and was still wrestling with his feelings for Madison.
The Bachelor host Chris Harrison therefore played matchmaker and set up a Peter and Madison reunion, which resulted in the pair professing their love for each other and deciding to give their relationship another shot.
"I honestly feel bad for a lot of the people that were involved," Kelley told E! News.
"I think it's best for Peter to take some time to be by himself and figure out what he's doing, reflect on everything that's going on and just figure out what he wants."
As far as her relationship with Peter's family goes, Kelley acknowledged, "Barb loves me, I guess I'm her favorite... She came up to me [at the finale] and told me, gave me the biggest hug and she was so sweet to me."
Although Barbara has received backlash for how she treated Madison during the finale and essentially scolded Peter for his decision making, Kelley still has nothing but love for her.
"I can't hate her when someone's so nice to me. Yeah she gave me a big hug, she's like, 'You're beautiful, I love you, oh my God, I was your fan since night one!' Barb I guess wants to get lunch with me and go shopping and hey, whatever, you know," Kelley said.
Now that Kelley is single and her time on The Bachelor is over, she revealed she'd be open to appearing on Bachelor in Paradise's upcoming seventh season.
"I don't think that I would ever shut down, like, if that opportunity's there then yeah," Kelley told E! News. "I haven't gotten past that stage. The opportunity hasn't even been there so I haven't even considered it, so we'll see what happens."
