"She's a good girl and perfect for him," a source told Us. "They have a lot in common, and he is crazy about her."
Magos, 23, is reportedly from San Diego, CA, attended Pepperdine University in Malibu and went on to work for Harrison.
Kenney, a 27-year-old digital marketing analyst from Scottsdale, AZ, was rejected by Hartsock in favor of Chris Siegfried, her final bachelor and current fiance, during The Bachelorette's August finale broadcast. He reportedly started dating Magos at some point in the past two months, as he alluded to the fact there's someone new in his life last month on Twitter.
"Most of me knows my vulnerability makes me human and alive, the rest of me is terrified of it," he tweeted September 23. "I guess that's why they call it falling."
Shortly before dropping his hint, however, Kenney had tweeted he was still single.
"No girlfriend for me yet, but let me know if you think you may know someone who could be a good fit! #stillsingle," he wrote to one of his followers on September 10.
In addition, another source is claiming Kenney and Magos are "just friends," according to Us.
