James Rousseau Disappoints Cranky Kate Bosworth

Kate Bosworth is possibly anorexic.

That's up in the air. She's definitely impatient and bitchy, though!

The moody, skinny Blue Crush star made it decided to make it a girl's night out after getting in a tiff with her boyfriend, James Rousseau.

According to the New York Post, Bosworth and Rousseau were spotted bickering at Seventh Avenue and 10th Street at about 7 p.m. Thursday. A spy's take:

"He was trying to hail a cab, but he couldn't get one fast enough for Kate. She then started walking away to hail a cab herself. She was p!$$ed!"

After that, she disappeared faster than the subject of a Criss Angel illusion. Just call her f*%k-'em-and chuck-'em Bosworth.

Later, Bosworth, who has been looking kind of healthy in recent bikini photos, was seen bar-hopping in the East Village with a gal pal.

That pal was Helena Christensen - who evidently had a limo, which picked them up from East 11th Street bar Angels & Kings at 11:30.

Too bad for you, James Rousseau. Looks like the only doggy style action you'll be getting for awhile is taking the pooch for a walk.
