Is she or isn't she?

Is Sienna Miller pregnant or not? That's what everyone would like to know.

It seems Sienna was going to walk the runway at Roland Mouret's fashion show next week but has pulled out (if only Jude had ;).

If she is pregnant, then this would explain why she went ballistic when she found out that Jude cheated (not that a girl needs to be preggers to be that upset when a boy cheats; sigh, it's always heart-breaking).

I really hope she is because they'd have beautiful little babies together. But then again, she'd be stuck with a cheater and once a cheater, always a cheater.
