'Twilight's' Alex Meraz to Taylor Lautner: 'Valentine's Day' movie 'lame and desperate.'

Alex Meraz, one of  the "Twilight: New Moon" wolf pack , snarled at his co-star Taylor Lautner on Twitter this week.

Inexplicably, he reviewed the trailer for "Valentine's Day,"  the romantic comedy Lautner stars (briefly) with Taylor Swift, Jennifer Garner, Jessica Biel, Julia Roberts, Bradley Cooper, Jessica Alba, etc.
