"Robby and I are not together," Amanda toldUs Weekly on Wednesday, September 6. "I'm not really sure how Robby's handled the situation."
Amanda, 27, and Robby, 28, were spotted together on numerous occasions this summer, sparking rumors they were dating. In addition to attending baseball games and mutual friends' birthday parties together, the couple had also been photographed walking hand-in-hand in West Hollywood, CA, in late July.
As shown on Bachelor in Paradise, Robby pursued Amanda intently for several weeks at Playa Escondida in Mexico.
The pair seemed to hit it off romantically following the temporary shutdown ofBachelor in Paradise production in early June, but their relationship was a slow burn since Amanda refused to rush into something again both physically and emotionally due to the way her engagement to Josh Murray -- whom she fell in love with on Bachelor in Paradise3 -- ended in December 2016.
Because Robby was friends with Josh prior to the taping of Bachelor in Paradisethis summer, Amanda confessed to the magazine she was "skeptical" of him at first.
"I wasn't interested in him at all and I was off limits to him because he's friends with Josh," Amanda revealed.
"We just kind of talked a little bit during the break and we just kind of enjoyed talking to each other, I think. And then we just started hanging out more and more and then it just started turning into something."
Robby said on The Morning Breath podcast in August that dating Amanda negatively affected his friendship with Josh, a 33-year-old former baseball player.
"We text here and there. It's definitely lost its spark," Robby admitted of the dynamic with his former close pal.
According to spoiler reports from earlier this week, Amanda announced her split from Robby during the live-finale taping of Bachelor in Paradise 4 on August 30 that will air September 11 on ABC; however, the breakup hasn't been publicly confirmed until now.
In a brief preview of the Bachelor in Paradise finale that aired following Tuesday's night broadcast, Amanda and Robby's relationship appeared to be on the rocks, as fellow contestants -- such as twins Haley Ferguson and Emily Ferguson -- were shown accusing the self-declared social-media influencer and former pro swimmer of cheating.
Reality Steve spoiler blogger Steve Carbone recently claimed that Robby was caught making out with a girl at a Zac Brown Band concert in July.

For now, Amanda told Us that she's focusing on her two young daughters, Kinsley and Charlie, whom she welcomed with her ex-husband Nick Buonfiglio.
"What people don't realize I think is, so my ex Nick, the girls' dad, and I have always been pretty cordial. I mean, we've had our moments where we haven't been," Amanda disclosed.
"But really for the most part I can say, since we split up almost four years ago, we've been pretty good about still being able to be around each other occasionally. I think that's really good and it makes me really happy that we can do that."
