WHATS MAKING TOM CRUISE CRY?

KATIE HOLMES confiding to pals she’s sick with worry after finding her usually super-confident hubby TOM CRUISE with his head in his hands, actually crying over the dismal flop of “Lions for Lambs” – which he starred in AND produced as his debut offering from United Artists, the struggling studio he took over a year ago.

Despite the star trifecta of Cruise, ROBERT REDFORD and MERYL STREEP, critics savaged the preachy-talky Iraq war flick as a boring “political science lecture,” and it tanked at the box office, grossing a measly $14 million – far from the $100 million-plus it needs just to break even. Shocked Katie, who’s seen only tears of joy from Tom when they wed and when baby SURI was born, told a source he’s not sleeping well and has lost his usual appetite for food. When she found him in tears, Tom told her that “Lambs” was a labor of love he truly believed would be respected – and he just can’t comprehend the negative reaction of critics and the public. Katie’s comforting him as best she can, but knows that only time will heal her proud husband’s wounds.
