Katy Perry shows off her new engagement bling! And her baby bump?

russell-brand2.jpgHot new couple Katy Perry and Russell Brand were spotted wandering around London over the weekend. 

And check out how she was showing off her new engagement ring. 

Is it a coincidence that she kept her left hand out in the freezing cold? We think not.

But the Dish Rag is far more interested in her other body language.

Why the hand on the tummy? 

Yes, it serves to show off her left hand and her ring. But could it also be telegraphing her Twitterized rumored pregnancy?
