He's among the biggest superstars in Hollywood, but Tom Cruise is easily dwarfed by his women. Katie Holmes towered over Tom in Washington, D.C., last night at the premiere of Tom's movie, Lions for Lambs. Is it the heels, or is she really a foot taller than him? Actually, she's only two inches taller than her 5'7" hubby. Maybe he should put on some thick-soled shoes to make up the difference. Meanwhile, Tom's even bigger ex, Nicole Kidman, who is 5'10 1/2", stood tall over her current love, Keith Urban, at the CMA Awards in Nashville last night, where Keith was in the running for entertainer of the year.
