Katie Holmes is wasting away!

According to Star Magazine, Katie Holmes has started to crack under the strain of life with Tom Cruise.

She often has dizzy spells and one source explained to Star that Katie has been suffering from headaches that make her see black spots and feel faint. Katie also seems to think that she has to be even slimmer and is obsessive about dieting.

Sources say that it is her need to live up to Tom’s expectations that has started to wear the actress down.
