Jennifer Love Hewitt has been romatically linked to her Ghost Whisperer co-star Jamie Kennedy. The 30-year-old actress, who split from fiance Ross MCCall in December, has grown closer to Jamie in the months since the breakup and the pair are now officially dating, Star Magazine claims.

“Jennifer and Jamie have grown incredibly close since he joined the cast of her show last fall. They hit it off right away, and her feelings for him have only grown stronger,” a source tells the publication. “She’s trying to keep her relationship with Jamie a secret, telling people they’re just friends, but she can’t hide her true feelings.”

The spy adds, “They work together all day and hang out most nights. And when they aren’t together, they’re constantly on the phone… Jamie makes (her) laugh, which she really appreciates after crying over Ross the last few months.”
