(People.com) -- Is Jamie Kennedy about to pull the plug on his relationship with Jennifer Love Hewitt -- and reconcile with his former flame, Shannon Funk?

Reports have surfaced that Jennifer Love Hewitt and Jamie Kennedy might be splitting.
While a new report suggests that Kennedy, 39 -- who began dating Hewitt, 30, last winter -- is no longer smitten with his "Ghost Whisperer" costar and is instead still hung up on Funk (a former assistant of Britney Spears), a rep for Kennedy told PEOPLE on Thursday: "There's no truth to this report."
And at the October 3 Tao/Lavo Anniversary party in Las Vegas, Kennedy told PEOPLE, "People just keep going on [with the rumor-mongering]. We know what we are."

So, is the couple happy? "Yes," replied Kennedy.
In the past week alone, the couple -- who denied engagement rumors in July -- have been spotted together on several occasions.
On Tuesday, they had a romantic dinner in Los Angeles. A few days earlier, on Saturday, Kennedy performed at the Laugh Factory in Long Beach, California, and brought Hewitt up on stage.
A Laugh Factory rep tells PEOPLE that Kennedy announced that "his eyes had stopped roaming and that he had no plans of ruining a good thing."
