JESSICA AND JUSTIN ON THE ROCKS?

JUSTIN & JESSICA HAVING 'ISSUES'?

Another rumor: Justin Timberlake's relationship with Jessica Biel has hit a rough patch.

A friend of Jessica tells the Chicago Sun-Times, "Things are not going as smoothly as [Biel and Timberlake] would want people to think they are" while on the other side, a Timberlake associate are saying, "I can always sense when Justin is beginning to get itchy in a relationship. … While he's still very public about being seen with Jessica, it's interesting. … He hardly talks about her when she's not around. The same thing happened with Cameron [Diaz, a Timberlake ex], and it also was the case with Britney [Spears].”

Still others are saying that nothing is wrong, saying, "I know they are both very good actors, but I truly think their feelings for each other haven't changed.”

AUTOPSY FOUNDS NATASHA RICHARDSON DIED OF "BLUNT IMPACT TO THE HEAD"

An autopsy showed that actress Natasha Richardson died of blunt impact to the head following her ski accident in Canada.

The specific cause was listed as "epidural hematoma due to blunt impact to the head," which led to profound bleeding between the skull and the brain's covering.

Meanwhile it was reported that the first paramedics who responded to Richardson were turned away, presumably because the actress felt fine at the time.

And medical experts say that could have led to her condition becoming worse because when there's bleeding in the brain, time is of the essence.
