Katie Holmes sparks pregnancy rumours

Katie Holmes has sparked speculation that she is pregnant with her second baby after stepping out in an outfit which appeared to reveal a "bump".

The Batman Begins star set tongues wagging when she arrived at the New York premiere of new film Hairspray in a figure-hugging black dress.

Her agent has denied the rumours, but the actress has made it clear that she wants to have another child with husband Tom Cruise.

When asked if the couple would like a larger family recently, she replied: "Yes, definitely."

The 28-year-old gave birth to daughter Suri in April last year.
