Jennifer Love Hewitt and Jamie Kennedy splitting up?

They’ve been notorious for their public displays of affection, but now it seems that the flame between Jennifer Love Hewitt and Jamie Kennedy may be extinguished.

According to a report, there may be trouble in paradise for the “Ghost Whisperer” costars, and infidelity may be to blame.

Kennedy is rumored to be cheating on J. Love with his ex-girlfriend (and Britney Spears’ ex-assistant) Shannon Funk, though nothing has been confirmed yet.

If that’s the case, it looks like the fairytale romance between Jamie and Jennifer may never make it to the 2010 engagement that Mr. Kennedy alluded to in an interview earlier this year.
