Katie Battles The Bulge!

Gains hefty 25 lbs. as time takes toll & Jamie parties with other gals

AFTER packing on more than two dozen pounds, movie beauty Katie Holmes has become obsessed with her figure and is working out like a demon fearing her career — and love in with hunky Jamie Foxx — will fizzle if her figure doesn’t sizzle, sources say. “Katie is pulling out all the stops to keep Jamie happy and spice up their romance,” an insider blabs.

“Katie’s big paranoia is Jamie won’t find her as attractive as she gets older. But she’s still desperate to keep hold of him and figures giving herself a body overhaul is her best shot of making it happen.”
