It's been all about pool parties and bikinis for Katie Holmes this summer! And there's nothing wrong with that—sounds like a pretty fabulous time to us.
But with every snapshot of this bathing-suit-clad babe, the buzz has been building about how thin Katie's been appearing...
This weekend, while hubby Tom Cruise was busy filming Rock of Ages, the 32-year-old actress stripped down into a skimpy black bikini before hopping into a Miami Beach hotel pool with 6-year-old Suri—and revealing a whole lot of, er, ribcage in the process.
Maybe Katie was just sucking in for a second or flexing her abs?
We hope so, because this doesn't look that healthy.
What do you think, is Katie getting too thin or is this sexy? Tell us in the comments.
