"This guy kind of committed suicide," The Bachelor: London Calling star toldPeople at The 23rd Genesis Awards in Beverly Hills on Saturday. "He's a nice man. I've met him quite a few times. But I think he should have gone about it differently."
However while Grant was harsh in judging Mesnick's decision to propose marriage to Rycroft during last November's Final Rose Ceremony taping only to later dump her on-air in favor of Malaney during January's taping of the season's After the Final Rose special, he also gave him props for recognizing the mistake before it got any worse.
"Ultimately, he had the [guts] to say, 'I screwed up,'" Grant told People.
As Mesnick and Malaney continue their romantic relationship, Grant told People he is still dating publicist Sarah Robarts -- who he first met when he hired her as his publicist after his The Bachelor: London Calling participation had ended with his engagement to Shayne Lamas.
