Whitney? Embarrassing. Pathetic.

That's how Danish journalists, including the Copenhagen Post, are describing

Heidi Montag

and

Spencer Pratt

have made it even easier for us to hate them. The couple, who staged a fake wedding in '08 as a publicity stunt, recently announced they are splitting up.

And Hills costar Audrina Patridge tells People that Speidi is "inseparable and in love."

Del Toro on his 'Hobbit' angst

Visionary Mexican director

Guillermo del Toro

(

Pan's Labyrinth

J.R.R. Tolkien

-est of all film adaptations,

The Hobbit

.

"My commitment to the project demanded enormous sacrifices both in personal and professional terms," says del Toro, who relocated his family to New Zealand, where the film is to be shot. But, says del Toro, his sacrifices got him nothing but interminable delays and scheduling problems so bad, it has made him want to run far, far away.

"Trust me on this," he writes, "leaving NZ and the Hobbit crew is extremely painful."

From kung fu kicks to heartstrings

Action star

Jet Li

, renowned for his mad kung fu skills, says his new flick,

Ocean Heaven

, which opened Monday in Hong Kong, is nothing like his previous action hits. It's a sensitive message drama about autism, said the star, who has dropped 18 pounds because of a thyroid condition.

"This movie is about sincerity," Li, 47, said, according to USAToday.com. "It shows that in this day and age that filmmakers are willing to do something for society."

In a shrewd p.r. move, Li hawked the film by taking a group of autistic adults to visit the dolphins at Hong Kong's Ocean Park.

"I hope everyone can examine what is the most important relationship in life - the relationship between parent and child," said the Once Upon a Time in China star.
