Speaking with New Idea, Grant, who accused the 32-year-old Bachelorette of cheating on him, says the story was a hot topic in the house between the contestants.
“I know that my name definitely is a subject of importance on the show because of what she did, as it should be,” he told the magazine. “I heard she sent a couple of guys home because of it, because they probably tried to get to the bottom of it.”
“I've never in my life seen someone come across as such a kindhearted and caring person and then turn around and do what she did to me.”
Grant's claims come after Ali gave her own version of events of their post-BIP relationship last week.
“It was so confronting,” Ali told TV Week magazine. “I went to Los Angeles and he wasn't who he described himself to be, nor did he live the lifestyle he said he did.”
Also speaking with NW last week, Ali says Grant's allegations and the public scrutiny left her “physically, mentally and emotionally broken” and described the weeks after he went public with the cheating accusations as “one of the darkest periods of [her] life”.
“We all have those exes that don't go away,” she added.
The Bachelorette premiere's on Channel 10 this Wednesday.
