Is Katy Perry pregnant?

Katy Perry has apparently been giving small hints of pregnancy on Twitter. The singer may be expecting a child with boyfriend Russell Brand. In a post addressed to the British comedian, she wrote: "i heard ur prego-ed".

Also, she has made similar suggestive entries on the web in recent past. " Let me tell you 2010 is BUMPIN!" the Daily Star quoted her as stating. Another bizarre message went: "I WANT IN N OUT!"

The couple, mostly seen together, recently visited India.
