London, Sep 16 (ANI): Rumours are rife that Angelina Jolie is pregnant with Brad Pitt's second child.

Recent pictures of a bumpy Jolie enjoying an afternoon boat ride with children Zahara and Maddox in Venice have fuelled speculations that soon there might be an addition to the Brangelina brood.

The 32-year-old star has been severely panned for her ultra-thin, skeletal figure, but the substantial bump under her figure-hugging dress in the snaps point towards a possible pregnancy.

The couple, who already have three children, Cambodian Maddox, Vietnamese Pax, and Ethiopian Zahara, as well as having one biological child, Shiloh, have never shied from admitting their wish for another baby.

"Brad and I would like to have more kids" Jolie told the Times in a recent interview.

"I've always wanted a big family. And Brad's the same. We are enjoying the children together. They are such big personalities, and it's so exciting to watch them grow up,” she added. (With Inputs from ANI)
