Buzz about an impending breakup between Jennifer Love Hewitt and Jamie Kennedy is just that – buzz, according to the Ghost Whisperer
"I'm not going to lie – it's not annoying, it's hurtful," Hewitt told PEOPLE Saturday at the Children's Institute Hosts Poker for a Cause in Commerce, Calif., to benefit Ghost Whisperer
costar Camryn Manheim's charity.
"It's really hurtful that people say that," says Hewitt, 30, who attended the event with her beau of 8 months, costar Jamie Kennedy. "Because he is like the most awesome person."
Adds Hewitt: "I really hate that people would make it seem like he's not really a good guy, and not treating me well. He treats me very well."
A recent report
suggested that Kennedy, 39, is still hung up on a former flame while dating Hewitt, a report Hewitt’s rep dismissed as a false claim by a disgruntled former employee.
"We are just trying to be really happy," Hewitt says. "It makes it hard to do that when everybody is putting negative energy out there."
Kennedy, who stood beside Hewitt, added: "I am lucky to be with her. And I love her very much."
